Ok so the racing season is starting soon. I need a rear end with trac-loc that i can put in the car. My question is, are there any rear ends that i can take from another vehicle that will bolt up with out hassle. Are axle shafts different size than a mustang, f-150, explorer? Thanks

You want a 3.55 LSD (K code) rear end from a CV/GM or town car. I found mine in a 84 town car and have seen them mostly in town cars and CV station wagons with tow package.2003 Town Car Signature - 3.27 RAR, Dual exhaust and J-mod - SOLD 9/2011

it would cost me more to put gears and trac-loc in my rear end than it would to go to a junk yard and pull one. 88grandmarq what years do i need to look for? 1980-1990Stock 91 Merc GM GS 5.0L EFI, AOD, 2.73 Open diff

K-code was an option on most cars, AFAIK. 82-83 was the the first year for the 8.8" rear diff. I have seen K-codes mostly in town cars and CV wagons.2003 Town Car Signature - 3.27 RAR, Dual exhaust and J-mod - SOLD 9/2011

'83 was the first year of the 8.8 and 3.55's, so '83-'91 will work for sure. I know the earlier 8.5 had ratios up to 3.42 and were available with a traction-lok, not sure about the 7.5's.
I've also heard '92-'02 rears bolt in as well (besides the brakes), but I don't know for sure.
If you wanna find a ring a pinion, just about any 8.8 will work. Axle shafts are a different story, they are different lengths and some are 31-spline (F150, Explorer) compared to 28-Spline. But I believe you'd be better off just finding a complete rear axle.1990 Country Squire - under restoration

If you use that car to race with, you may think about getting a w-code(3.73 locker). You'll feel a big difference in acceleration, but your highway economy will dive some.88 Town Car (wrecked, for sale)

W code was only used in 87-88 turbo coupes with automatic trans. while it is a good gear, the diff assembly will NOT bolt into the panther platform.
your best bet is find a K code in the junk yard, rebuild the traction lock on it, replace the axle bearings and seals then bolt it in the car. cheap and easy2003 Town Car Signature - 3.27 RAR, Dual exhaust and J-mod - SOLD 9/2011

I'm not sure of the ratio SuperCoupes used, but they have IRS. They do use an 8.8 center section though.1990 Country Squire - under restoration
