Ok Ive heard that automatic fc's came with different diffs than manual fc's. Somethign like the autos had a 3.9 while the manuals had a 4.1. Does this apply to the lsd's too? Im asking because i have an 86 base that i converted from auto to 5spd and am about to swap in a lsd from an automatic gxl. How much of a difference does the gearing make?

yes they did. Why didnt you just ask me dude. I got the diff you wnat to buy lol.

Only thing ive heard is thta teh acceleartion is a lil slower with the 3.9 than the 4.1. , but you get more torque out of it in the long run.

Yo i didnt know your car was automatic and converted to manual..

Yes you will have a 3.9 rear end gear. It applies to all diff's. I had a 3.9 LSD in my sport back in the day too. It makes a measurable difference in speedo readings. Semi-noticable difference in driving.
