is there a difference between the 89-91 na and t2 rear 4.10 limited slip rear ends ? if so what and will an na rear work with a t2 drivetrain .. thanx

 

N/a's have a 7" ring gear, TII's have an 8" ring gear. They also have different flanges. Its all or nothing, unless you custom make some stuff.

 

So is that the $100 vert?

 

Yep, thats it. Heres more pics if you want to see.

I hope to be coming down to jax soon, but I dont know which car Ill be driving. The vert needs some work before I can drive it, like a new top, and fix the pass side window. Ill make sure Brian tells you when Im coming down, if I dont tell you.

 

The only series 5 NA to come standard with a LSD was the GTUs and the gearing on that is 4.3 not the 4.1 like the T2. (although there is some rumor saying a few loaded with every option coupes in 91 had the 4.1 LSD rear ends as well- can't confirm that though.)

The T2 rear end was also designed with bigger halfshafts and a different driveshaft flange.
