get the gears from a caprice - 3:42 gears. It'll fit your car. I asked over at the realoldspower.com forum, and that's what they recommended. Basically, anything that will fit an 8.5 inch driveshaft. And let me know what you have done with yours, since mine is a 1990, all the same under the hood, and I've been trying to eek out more power. (yea, it's a 307)

Keep in mind that unlike a Caddy, some Caprices/Deltas had 9" brakes and therefore the small bolt pattern on the axles. I've wondered myself if the Caddy axles with the big bolt pattern will slide into the spiders on a carrier that had small axles. Anybody know for sure?

I thought 1990 brought the FI 305/350?

nope. the 91 had the 305, but the 90 has the 307.
