Yes and no. It will bolt in, but the Fleet has four channel ABS (sensor on each rear axle), while the SS has only three channel ABS with a single sensor in the middle of the center section. SO, the Cadillac ABS and traction control will not work.

really? i thought there was a 1/4" difference on caddy? :dunno:
Negative. You can put Impala SS rims right on a Caddy with no problemo. ;)

However, there is a difference in the bolt pattern of the 80s cars vs. the 90s cars. :cool:

yeah i was thinkin they were 4 3/4" and caddy was 5" (well atleast the metric size of that lol) i thought you still used the biggest pattern on the k/o adapter for fleets-or did the ss come out with the 5" as well?

Now that I think of it, I have a set of 9C1 (cop car) wheels that I also used to use as winter rims. :cool:

will a 96 impala with disc brakes differential fit on a 2 door 82 fleetwood caddy?
Yes, but you will need a slightly shorter driveshaft.

Technically, no. GM didn't use a different prop valve on the 94-96 Caprice cop car or the SS. As a result, the rear brakes don't do much (discs use more pressure than drums). To get more pressure to the rear discs, google "stealth bolt mod".

the impala ss rear end with disc brakes is a total of 1" wider than a cadi drum rear... i think the difference is in the brakes because the rear ned housing looks the same... i was going to do the conversion but had the 2 rear ends next to each other and realized the ss rear would make my tires rub on a big body cadi.
