was hanging around dr diff's website and ran across a wide selection of new ring and pinions for the 741 and 742 very reasonable prices....I remember a post a while back where a guy was having problems finding 3.23 for a 742 new http://www.doctordiff.com/8-3-4-ring-and-pinion.html

is this rear anywhere near the width and spring perch location of an A body, i believe it has a 3.73 in it??

I've got a 91 Dakota with a magnum v6 and a500. I drove the truck to my house. MY brother bought this truck new and its been in the family since. I have decided to part it out. The tranny is the one with the dash button to engage/disengage the od. There is absolutely nothing wrong with the...

the 8 3/4 i bought complete drum to drum with single 3.23 was supposed to have come out of a 70 duster, where would i look for id markings to verify year and such of manfacture ????????????????...it has a 741 case

Ive got a 742 case 3.91 gears sure grip that is dissassembled and needs clutches and spider gears. The guy who is going to rebuild it said that for 150 bucks he will reassemble the chunk (no new bearings install , (yea I know pay now or pay later...)) with all the new stuff and set the lash...

I have no idea what this is supposed to fit, I tried to do a trade deal with a buddy and told him that it was supposed to fit a 70 Dart and he said it was the wrong assembly for that year. I bought it supposed to fit my 70 Dart

I found out the hard way that there are several sets of brake/clutch pedals combinations out there. I had assumed that they were all the same from 67-76. can someone shed some light on this for me?

Just did a bunch of research, on 360 Magnums up to 96 the torque converter was balanced with weights, after 96 the balance was in weights on the flex plate. So if you want to run a neutral balance converter like I have that has no weights you will need the 97 and up weighted flex plate. If you...

Guys I.m putting the speedo cable hookup back in the trans. I have a 28, 29, and 31 tooth plastic gears to use. I have a 3.23 rear ratio and 25.1 tall rear tires. Which one would be closest to being accurate? The 29 was original on the 2.76 original with e/70/14 tires.

, came off running motor, ready to slap in, 35 plus ride also small block dizzy 15 plus ride OR Trade

To make a long story short I sold this and now have it back. My question is I originally sold this thinking it would be too loose for street manners in my Dart with 3.91's. Does anyone have experience with this converter on the street ? I'm really concerned that I will be cruising around town...

Finally got this rascal in. Yea I know I missing the backing plates, axles and 1 mounting stud, I have all of that I just don't have them put on yet. 3.23 ratio , I'm rebuilding a 742 case 3.91 sure grip I will put in down the road I'm hoping to finish the rear up tomorrow hope to install the...

Is this combination of parts correct?? I don't want any vibration ...... 360 Magnum factory flex plate balanced to the engine by the factory, slant 6 converter with no weight. 904 tranny, Professional Products balancer for 360 Magnum. Cheetah reverse manual valve body

Putting a 360 Magnum with a 904 with a reverse manual valve body in a 70 Dart and the stock style trans crossmember rubber mount doesn't look like it's going to cut it. I would appreciate recommendations for a really good mount that doesn't cost a fortune.

Hey has anyone out here run a b an m megashifter with a manual reverse valve body. I called b and m and they said the ratcheting action will work in reverse as well as forward??

Need help identifying the year 904 I have so I can order the appropriate rebuild parts. The raised numbers on the case are 452-9, the numbers stamped in the pan rail are 3681063 3144 9585

I pulled the valve body off of my 904 tonight to put on a cheetah reverse pattern body, I didn't pull it completely apart but was noticing that it appears that there isn't much meat left on the bands. I was suspicious of this as the guy I bought the tranny was real sketchy on how many miles...

I want to go from a 742 case factory sure grip 3.91 to putting the sure grip unit in a 741 case with 3.23's what do I need to do to make this happen??

Want to sell not sure of value lil help please.

Could someone help me settle an argument please. I say that the torqueflite trans will shift at a predetermined rpm even WITH a shift kit and that you can only hold it in gear as long as you want with a valve body. Last I rememberd the Hemi 727 governer was the one set at the highest shift...

How can I tell if my 904 has the 2.74 low gear or not without tearing it down?? I read in a thread that all 904's from 1980 up had the low gear. Is there a reference somewhere that I can get the numbers off the tranny to tell me what I need to know??

Im going wed to look at a 66 DArt to buy and strip to sell parts off of. It has a 8 1/4 sure grip 3.23 and 73 front lbp pattern disc setup complete. Can someone give me a ballpark what these are worth??? I will be advertising them here and am not trying to get rich just make a few bucks and...

I called B&M to ask about mating my 360 Magnum to a 904. The tech guy told me that the flex plates for 360 magnums were matched to each particular engine by either weights OR by holes drilled to balance it.He also told me that the earlier magnum engines had on hole offset in the flexplate and...

Are the axle splines different in number depending on the case number. For example I have some small bolt pattern a body axles that I think are 29 spline. They fit into a 741 chunk. However when I start shopping around for a posi carrier I see some that do not say how many splines and some that...
