Rear end
Ok so driving my 83 agian for the first time in about a year, has given me very mixed feelings on selling my rex's. I really do want a new car but I would have to get rid of all the cars I have now. Anyways I have a 85' with a 5.12 LSD in it and was wondering if I can take the gears from my stock lsd and put them in with the lsd? So I would end up with like a 3.98lsd or whatever stock 83' non lsd rear is. Because the 5:12 is to much rearend for street you run out of steam fast you get to that point fast but its just not practical haha.

SO you have a 3.90 with an open rear, and a 5.12 on an LSD and you want to end up with a 3.90 with the lsd? Yes you can swap the LSD into the 3.90 diff. But you need the tools to measure and do it right. Read how to setup a ring and pinion in the FSM. See if you can tackle it.

Haha I think I might keep the 5:12 everyone and their brother is trying to buy it off me. Neven know when I might want to do some serious drag racing 
. Anyways I probaly would just have my buddy's dad swap it for me. He has a trans shop and could do it. Thanks for the info. I also have a welded 4:88 but dont think I want to use that because the car is going to see street time.
