Re: new to this
Your car will have a 7.5" 10 bolt differential. I can't tell you what gears it will have without more information. It'll be 3.23 or 3.08 unless it's an IROC, then it'll have a couple of other options.
Engine (probably be a 305), transmission (A4 or M5), induction system (carb, TPI).
You can also look up the RPO code if they're still in the center console to see what gears the car originally came with.

Re: new to this
If it's an IROC,that came with TPI, and was built late in the production run, it could have the Australian 9-bolt. That should be 3.27:1
