What parts are in it?

Im trying to find out more about my 1990 GTA, specifically about what major parts are in it, and hoping I can find that out here. The car as far as i know is stock.

What i know for sure:
Year: 1990
Engine: 305 TPI LB9
Trans: 4 speed auto
VIN: 1G2FW23F3LL213651

I was able to use the VIN to find out the engine model, but thats about all.

What i want to find out are:
- what heads does it have (081?)
- transmission (700R4?)
- rear diff (POSI 2.73?)

Is there anyway to find this out without getting under the car and looking for stamped part numbers?

Thank you
