I know the rear is wider by a few inches, but will there still be enough tire clearance in the wheel well? and does it still bolt up to the rest of the car? I know the drive shaft also has to be shortend too. the car in question is for my 71' scamp.. 1971 Plymouth Duster 340 auto 1937 Plymouth PT50 1969 Dodge Dart Swinger 340 4 speed 2013 Ram laramie 2500 hemi 2008 Harley FLSTSB springer

Not a big deal if you can weld, and the new perces are about $13 from Mopar. I have seen F-body rears in Dusters and Demons/Dart Sports, but they have an open wheelwell. The "slab side" A-bodies (Dart, Valiant, Scamp) dont have the room for a wider rear. Its not worth the trouble. Get ahold of an A-body 8 1/4 rear. They are still pretty easy to find 1969 Nova 454/M21/3.31 Mild mid-11 second weekend cruiser 1994 F150 XLT Super Cab 2WD 5.0/4R70W/3.55 (Daily driver)

IIRC he found an 8-3/4 which was what he was originally wanting.

I bought the axle being told it was for an A body, but after some measuring found it was wider than what I was really needing. aw well I guess. thanks again 1971 Plymouth Duster 340 auto 1937 Plymouth PT50 1969 Dodge Dart Swinger 340 4 speed 2013 Ram laramie 2500 hemi 2008 Harley FLSTSB springer

I can run my 78 LRT's rear tires and wheels under it, 275/60 HR 15 on a 8" rim if its only me and the wife in the Cuda. If I have a rider in the rear the tires rub on the springs. It does fit on the stock springs without binding. I have run it this way for 8 years and 50,000 miles. Just for info, I am running a 3.55:1 Suregrip from a 8 3/8 Dodge Van in the 8 1/4 housing that came with 2.94:1 open gears. The truck 8 3/8 is the same as a car 8 1/4, go figure.

DaveJ I just want to add to this to clearify. I removed this rearend from outunder an Aspin R/T. I did not figure it had been changed as it was just as rusty as the rest of the car. 90% of the Aspin R/T was gone.
