Hey guys,

I have a 1971 Plymouth Satellite. Last year, I upgraded to a Magnum 360 from a 1995 Ram pickup.

The factory rear is 8 1/4 with 2.76 open gearing. I've been checking around and wanted to upgrade to 8 3/4 with a suregrip. 3.91 gears would be preferred since I intend to go fuel injection and also use a truck tranny with overdrive at some point. Anyway, finding a rear, with good gearing and the suregrip appears likely that it will cost several to a thousand hundred bucks...

I used to mess with Lincoln Mark VII's and I have a parts car with a limited slip 8.8 (disc brakes) and 3.27 gears and 5 on 4.5" bolt pattern.

Has anyone done this with success? What would be required other than welding the spring perches on the rear? I looked online and the rear end width listed for the Mark VII was 61.25" and I showed the 1971 Satellite to have a 63" rear. I was thinking for about 1/2 the money, I could have 4-wheel disc brakes... Am I delusional? Thoughts? Ideas? Suggestions?
