RX7 rear diff question

I have seen a few comments posted on here about people putting in an RX7 chunk into the factory B2200 rearend. I was wondering what years RX7's would be applicable?
I am looking to put a limited slip differential in my truck.

This should help answer your question...

Perfect! Thanks so much!

I've been doing some more research on this topic and wondering if anyone ever used a 3rd member from an 82 RX7 with LSD?
I know the 84-86's work in the B2200's.
The TII's work in the B2600's.

But do first gen RX7's chunks fit?

I want to say yes, I've got a buddy who used a first gen, but I dont know exactly what he did and how for it to work.

I have a lead on one from a fellow coworker. I asked him to take a picture of it. I should be able to determine if it will work by looking at the pic

Iv heard the 1st gen rx7s have 407 gears limited slip and willb2200

Well I've heard that if you eat four quarters, you'll shit out a dollar bill. Point being, don't believe everything you ever hear.
The first gen RX7's will not work in our trucks because they have a 24 spline axle and our truck is 26. And the gear ratio you are referring to is the 84-85' GSLSE, which is what I have in my truck.

Ask me how I figured this all out the hard way. I bought an 83 (first gen) and it didn't fit because the axle splines were different.

Edit: I meant to post this link:

Fucking Kovz! You really know how to turn a phrase! Back on topic though will newer rx7 3rd members fit in our rear diffs? Just wondering. And thanks mike for giving me a laugh this morning!!!
