80’s Firebird rear end, 5 lug(bolt pattern same as MGC 5 lug), disc brakes, limited slip, “3:3/1 I think”, and mounts to fit rubber bumper MGB (this may be the same as the chrome bumper?). The brakes will need a proportioning valve in line when you set up the new lines. $1200

Your ad on MGExp says 52" wide. 53" or 52"?

Given the high cost of truck freight for this unit, I would offer $700 for it providing its length is 52" and it is around a 3.3 ratio. My reasoning is that I have been strongly considering a Quaife LSD installed in my MGC 3.07 axle which would cost me about the same once shipping is thrown in.

Not sure how I miss measured, my flat edge may have been on a stud. Wheel mating surface to wheel mating surface is 50.5".
3 and 1/4 turns of the driveshaft to turn the wheel.
It is a 10 bolt rear end, I am going to try to identify whether it is a 8.2 or 8.5...

It is neither.

It is either a 7.5" or 7.625" (if '86 or later).

$500
I am selling this to help offset the cost of sending a really nice b motor to a shop to be assembled so I can drop that in my car. Someone with a nice v6-or v8 project needs this more than I do.

Still available. PM me if you need specific information, such as numbers stamped on the housing or need something measured, calculated...
