If the trans still has the sticker on it, you can identify the final drive. Some say that there is a set of numbers cast into the bellhousing, also that identifies it. The bellhousings for all the Fiero transmissions have the same bolt pattern and will bolt to the 3.4, 2.8, or 2.5. I believe there has to be a little grinding done to mount the Th125 to a 3.4, though. One of the axel shafts has a different spline, on the 84 trans and you'll need to purchase an 84 axel for that, if you're installing it into a later year. Looks like all yours are 84 though, by your signature.
I currently have the 4:10 behind a 2.8. In a recent event, I filmed from my car. Upon reviewing the film, I noticed that in changing gears, you could see the front of the car lift, even in 4th gear. It does offer quick acceleration. Since I was told that this was a 3:32, and it wasn't, this trans will be up for sale soon. I've only run it for about a month. All new seals, and the requisite New drive axel with CV joints comes with it.
