what do i have, what do i need?

[turbojeep68]

where is the best place to find out what i have. just got a partial turbo setup. some parts missing and need to know what all i need.
the two part numbers i have found are 1261620, 25501542 and turbo says "AIResearch". I have the intake but cant see any vin numbers on it yet. I also mave a 76 buick 3.8 and not sure if the turbo will go on it. So where should i start
All i know is it is a carb setup, missing one exast header, carb, crossover and down pipe. other than that i know nothing about the setup or what else i may be missing for that mater.
OH, and how free should the turbo spin? It dont spinn to well.

The turbo should spin freely.
