rear diff.
Hello board:
Does anyone know if a rear end from a 1991 350 cadillac brougham bolt into my 1984 chevrolet caprice?The rear thats in the cadillac is a 8.5 10 bolt with 3.08 posi. the tread width is the same and from eyeballing,looks like it will work,but I am not sure.What Say You :O: Mighty Board? Thank You All

Re: rear diff.
Also you will need to have the driveshaft shortened. The 8.5" rear is deeper than the 7.5 or 7.625 rears.
All of this, including silicon212's answers, assumes you do not have a wagon or 9C1.

Re: rear diff.
I think it should work. The Cad would be a D or C body. But the only real difference between the B and C/D bodies is the wheel base. Everything else should interchange.

Re: rear diff.
What did he say? I missed that...
 The other wildcard is the transmision. I can just about guaranty the Caddy has a 4L60/700R4, but the '84 might have a 700 or 200. Could get really lucky, or you might be making a driveshaft. If you do it, take the Caddy driveshaft so you have the right yoke.

Re: rear diff.
Just for clarification, F-Cars only got the TH200C, (never the TH200-4R) and only in their darkest, saddest days. By the time the little weakling transmission was turned into an overdrive unit (200c -> 200-4R) F-Cars thankfully only got the 700-R4. The only exception to this was the handful Buick powered F-Cars in '88-90, since the TH200-4R had a BOC bolt pattern.
