They are good rears but hard to come by, I've seen 2-3 in the past 15 years that weren't in someones driver, I ran 8.75's until about 3 years ago when I started looking around for a budget friendly alternative.

64-66 Mustang/Falcon & 75-80 Grenada/Monarch use the same 5 bolt pattern and spring perch spacing as the A-body. Supposedly, 64-65 Comets would work, but I can't verify it. These cars had 8.8 as well as 9" rear gears. Some of the early I-6 cars had four bolt wheels, so don't get giddy until you check it out.

The "brass ring" of these rears is the 77-80 Lincoln Versailles. Not only do they have the right bolt pattern and spring perch spacing, but they also had disk brakes. Production numbers are very small, so good luck finding one.

I forgot to say is a 64 falcon 8" rear end thinking swap on my 66 dart,thinks it bolt in direct to?
 
I put an 8.75 under my last car - then bought axles (Moser) and had them made with 5 on 4.75 pattern (yea, typical Chevy) - mounted Wilwood disc brakes on it too... too bad you are in Cali. - I still have it and would sell it.
 
Hey thanks 2 Darts,but the bottom line is that rearend bolts on perfect with out any welding or removing leaf springs mounting brackets?

Most of the early V8 fords had 8" rears, the 9" that came in them stock wasn't great either, it had small axle bearings, 28 spline axles, etc.

The 8" is decent, I knew of someone running one in a valiant and it worked fine, if you're putting out any power run a 3.70 or taller gear, 4.10's and 4.62's have a really small pinion gear and it will snap off the stem if you abuse it.

I don't need to replace perches?

I have a 67 Dart. I would like to swap out the rear end. What other rear ends will fit? Doesn't have to be a Mopar Rear end. I would like Posi and a larger lug pattern as I have the smaller 5 lug 4 1/4 I believe. I am looking for maybe a Chevy lug pattern of 4 3/4.

A mopar rear would be great too if anyone has good suggestions.

Thanks,
Mark

first thing to check when swapping other rear axles into your dart is,,, pinion offset ,,,of the housing you will use as compared to your stock housing ,, you want the pinion offset to be as close to your stock set up as possible -- so your driveshaft does not run at a weird angle .
having said that here are some measurements so you can compare them and make your decision on whether to go this route or find a A-body 8-1/4 or 8-3/4 or have a custom housing built
A body width --- axle flange to axle flange 58-5/8 inches approx. --- axle flange to center line of pinion,,, passenger side 28-3/16 inches,,, driver side 30-7/16 inches -- spring perches 43 inches on center.--- small bolt pattern

1965 -66 Mustang 8 inch ( weak axles ) and 1975-80 Granada/Monarch drum brake 8 and 9 inch axles width -- axle flange to axle flange 57-1/4 inches approx. . ---- axle flange to center line of pinion ,,, passenger side 28-1/2 inches ,,, driver side 28-13/16 -- spring perches 43 inches on center -- 5 on 4-1/2 bolt pattern.
1977-80 Lincoln Versaille 9 inch axle a bit wider due to disc brake thickness

1967-70 Mustang/ Cougar 8 and 9 inch axles width -- axle flange to axle flange 59-1/4 inches approx. -- axle flange to center line of pinion ,, passenger side 29-1/2 inches ,,,, driver side 29-3/4 inches ---- spring perches 43 inches on center -- 5 on 4-1/2 bolt pattern.

1970-74 Maverick/ Comet 8 inch axle width -- axle flange to axle flange 56-5/16 inches approx. --- axle flange to center line of pinion ,,, passenger side 28-1/2 inches ,,, driver side 28-3/16 inches --- spring perches 43 inches on center --- 5 on 4-1/2 bolt pattern.
these measurements will vary by about 1/16 inch due to production tolerances
in the above posts there seems to be confusion concerning 8.8 rear axles which have rear cover and the 8 inch rear axle which has a drop out center section,,, 2 completely different rear axles.,,,, late model ( 1968-80 ) 8 and 9 inch 28 spline axles are good to about 450-hp

What gear ratio? Strap it to a pallet and ship it?

3.23 - do you have access to a loading dock?

Maybe, how much do you want for it?

I'm pretty sure I could arrange the loading dock part, just haven't needed to in the past.

THE Comets, Mavricks,Mustangs,Grenada USED 8" NOT 8.8 REAREND as week as the 7.25. very rare but some had 9" rears
 
Remember too that the pinion is offset by 1 1/2" on a Mopar rear end, and shortening the 8.8" explorer rear end results in the correct offset by using an extra short side axle and shortening the housing to fit said axle! Then the perches need to be moved as well!!!

So is the ranger 98 8.8 rearend the same as the explorer cause the rear diff I got is a ranger rear diff
 
This 66 barracuda is so stressful trying to find what will and won't work and then the 440 swap into it I know my son will try his best to accomplish this I just hope he doesn't give up
 
All this work and time and if something is misaligned, warped from heat of welding, etc. etc. you end up with a vibration or drive line noise that won't go away and you can't fix....sometimes it is better to just spend the extra money and buy the right rear that will bolt in directly with absolutely no modifications....my 2 cents

I have to disagree with you here. If the spring perches on the b body rear are moved in half an inch on each side it's a direct bolt in with wheels with proper offset. More do it yourself types can reweld perches than can shorten and balance driveshafts.And it stays all mopar.

Daredevil are you saying I can get rid of my 7 1/4 and have a bolt in ready replacement without shorting my axle?
 
I'm interested. After a long wait on a 8.25 he changed his mind. Rebuilding a 65 Dart GT 273 Go-Go Package. The 7.25 is trashed and no luck for a 8.25 or 8.75. I wanted the 5 on 4.5" LBP. I got it in 2011 when the P.O used the good parts to restore a Charger GT and put 66 doors and trunk lid on it. I'm at the point of putting anything in it or parting it out to get my money back.
