Problem
I have the gears that were in it ...before I started rebuilding it...lol. This tranny is out of another car. I'm going to try and match the stock 27 inch tire height. I'm looking at getting the 17x8 or 17x9.5 torq thrust d's. What is the tire height that you guys are using to get a good fit in the wheel well?

I'm guessing you're running 225/70/R15? It has a diameter of 27.4".
If so you can run these to acheive similar OD:
255/55/R17
255/45/R18
Both have a dia of 27.0
Here's a cool link to determine tire size:

Also, I would call these guys to figure out your speedo gear situation. They have helped me in the past.
