Nope never stock, and there is no such thing as an LSD aftermarket or OEM to fit in the 4spds. Yes you can 2 tire fire with and open diff in a Fiero. I have the video to prove it.

Cheapest route is to buy an entire 4cyl 5spd car, move all the 5spd parts to your 85GT, then part the rest of the car as spare parts for your car, then scrap what you don't need. I routinly see buggered up 5spd 4cyl cars in the $200 range. Just look for one that has been hit or has a blown motor. The Isuzu 5spd is fine for a stock or semi stock V6. I ran them a lot on my V8. I am moving to a Getrag 5spd in my V8 car, the Getrags are hard to find and usually fairly expensive.

ya but if i take the 5 speed out of a 4 cyl car will it bolt right up to the v6 engine or will i ahve to do some mods and stuff, cause i have a isuzu sunrunner just sitting around at my house. would that one work? or capt fiero, when you end up moving to a getrag ne chance you will be selling one of the ones you have now?

The Fiero Isuzu is a direct swap, you just have to have the matching shift cables, brackets and such. It bolts up just fine. The reason I am pulling the last Isuzu out is I blew it up again. 300+ lbs of torque is just too much for the Isuzu. I posted an add on Craig's list for just the cables for $100 but if a club member comes forward, I can include the cables, 5spd shifter and any related bits for that price, however donor Isuzu 5spd you will be on your own to find. For the record only the Fiero Isuzu is a direct swap, your sun runner is not.
