    Any idea where I can find a spindle for my 1970 plymouth duster

    Close. It is actually called a "knuckle". The spindle is the part the rotor rides on. Most people incorrectly refer to the whole thing as a spindle when in truth, the spindle is part of the knuckle. It is sort of like when people say cement when what they should have said is concrete. Cement...

    Spindle Replacement

    I am the guy that doesn't toss a bone that still has meat on it. It isn't as if I am broke, I just don't throw away stuff that still has life to it. To be specific, the red arrows are pointing at the knuckle, the yellow arrow points to the spindle on the knuckle. Again, these are really...

    Spindle Replacement

    I don’t like those gouges but if the bearing mounting surfaces are fine, I don’t think the area in between matters. Nothing makes contact with the area in between. I pack my knuckles and rotors with grease in there. The knuckle and spindles are really strong. I have an A body set on my Charger...

    Spindle Replacement

    You use big words to object to the use of a correct term.

    Spindle Replacement

    I’m curious what is wrong with what you have. Technically, you are referring to “knuckles” not spindles. Regardless, it takes a lot of impact to damage them. Pictures would help if you are set on replacing them.

    Disc Brake lower balljoint question

    Hey, I wasn't criticizing your use of English, you write fine from what I can tell. Most people refer to the unit as a "spindle" but it isn't the correct term. It's just like calling a limited slip differential a Posi when the correct term for Mopars is Sure Grip. Are you sure? I'm not. I've...

    Disc Brake lower balljoint question

    Moog used to be the best. Nowadays, they are sometimes good, sometimes crap. Take a look at this lower control arm bushing: Yeah...that bushing is off center. GREAT quality there, guys.

    Disc Brake lower balljoint question

    First, there are proper terms to use. The red arrows point to the steering knuckle. The yellow arrow points to the actual spindle. If you have steering knuckles like these, you need the 1973-76 A body disc brake lower ball joints. The B and E bodies use the same ones.

    Electric Vacuum pumps

    I know a guy with hydroboost in a 65 Coronet. His works well. I don't know him very well though.

    Electric Vacuum pumps

    I was given a new Hydroboost unit for free on the condition that I install and test it and give a review on what I did to make it work. I got almost no help from the supplier since the deal was that I was supposed to be doing the research and development of it. I measured and fitted the lines...

    Electric Vacuum pumps

    I have one in the Charger, 4 wheel discs in that car. The pump is routed through a fuse. It works fine but I too worry about reliability. I tried that, I couldn't get the system to work. I wore out 3 power steering pumps trying to get the HB unit to provide boost before I admitted defeat and...

    What is this?

    Cars with front disc brakes use a proportioning valve. 4 wheel drum cars used a distribution block. They are not the same thing. Distribution blocks look like this: Proportioning valves look like this: The proportioning valve for disc/drum systems has a few functions. It is designed to...

    73 duster front brakes locking up when coming to a stop.

    I don't know about that. A guy I knew that once lived in this: He owned this car: One time we were heading south to go to the annual Spring Fling in Van Nuys, CA. He drove his car, I drove this: We stopped for gas and I saw grease coming out of the front hub on the right side. He...

    Early A, 9”……if it was yours, take $ out of the equation, whats the best solution for brakes

    It is personal taste, that is for sure. I do like the steelies and hubcaps on early to mid 60s cars but not so much for the say...69 and later cars that had more exterior trim and garnish. I think the rallye and road wheel are excellent on just about anything from the mid 60s and later.

    Early A, 9”……if it was yours, take $ out of the equation, whats the best solution for brakes

    If my vote counts Zach, I like the 15" wheels painted body color.

    Early A, 9”……if it was yours, take $ out of the equation, whats the best solution for brakes

    I'd skip the rear disc brakes. A disc/drum setup is more than adequate, simple and easy to find. Rear discs are great for looks and ease of service but unless you're properly proportioned to the rest of the system, they are dead weight. The reason new cars have 4 wheel discs is partly weight...

    '72 Scamp Can I just fix the front brakes to get it home?

    That is a misleading statistic. MOST of our travels are close to home so naturally, most of the accidents will be too. Did you know that most vehicle accidents occur to automobile drivers? There are MORE cars being driven than motorcycles or skateboards!

    '72 Scamp Can I just fix the front brakes to get it home?

    For the record, the thing that some people are calling the "emergency brake" is NOT actually known as that. It is a Parking Brake in all of the factory literature and even written on the handle. It engages one of the brake shoes on each rear wheel and provides vey little actual braking in panic...

    bigger rear disc in rear than front a problem I assume?

    Well, ****...I do agree with all of that.

    bigger rear disc in rear than front a problem I assume?

    Before I optimized my combination, I had Cordoba 11.75” front discs, Dr Diff/Cobra 11.7” rear discs but the caliper sizes were vastly different. Fronts were the 2.75” single piston design used from 1976 onward. The rears were 1.5” single piston. I was at a 3.3 to 1 ratio and while the car...

    bigger rear disc in rear than front a problem I assume?

    I agree that the lever arm of a larger rotor does have an impact but if a tiny caliper is pinching a huge rotor, I don’t see the rotor size slowing the wheel any faster. A tweeker with a 3 foot breaker bar won’t crack a nut loose quicker than I could with a standard ratchet. There is a...

    bigger rear disc in rear than front a problem I assume?

    Finally, someone understands and offers to chime in. You could have rear rotors twice the size of the front and it wouldn't matter as long as the caliper size is proportioned right. A common guideline for a 4 wheel disc system in a well handling car is a 2 to 1 brake bias, front to rear. You...

    Im convinced there is so much bullshit with these companies Right stuff is a joke

    Most of the time, you will with a 4 wheel disc arrangement given the large size of the caliper pistons. I ran one for years. It was not a problem but my rear brakes had a small caliper size. A larger bore requires moving a greater volume of fluid but if you keep an eye on the fluid level, it...

    '73 up drum to disc conversion track width change

    That TSB states a 3.6” difference between the front and rear track? I knew the front was wider but that is a stupid example of engineering. I have put the 68-70 B housing in Dusters a few times and it really evens it all out nicely. 3.6 inches??? What the heck ???

    '73 up drum to disc conversion track width change

    No, not entirely true. The B body axle had the spring mounts at 44” center to center. The A body is 43”. I’ve heard of dudes just spreading the leaf springs to mount a B axle but to me, that is a hack move for dudes that don’t have a welder.

    '73 up drum to disc conversion track width change

    Yes. Dusters and Dart Sports always look weird when fitted with stock width wheels because of this. The bulging quarter panels make the rear wheels look recessed. The front track got wider with the front disc brakes and actually looked good while the rear wheels tucked way in looked like a big...

    '73 up brake distribution block/proportioning valve question

    This is written like Richard Ehrenberg writes and just like him, it only tells part of the story. True, the 4 wheel drum cars do NOT have a proportioning valve but they DO have a distribution block where all the lines converge. To some, they might think these are the same thing. Telling the...

    Members with 4 wheel disc systems: Can you lock your wheels?

    If you want to grip, you need tires that don't slip!
