Then he told me 'Yea, the stock rear end'. I later found out that he thought the stock rear end was an 8.8" and thats why he told me thats what it had. So should i go through the trouble of getting rid of the 7.5"?

Hell ya, I would. I am actually. More strength, less flex, u can buy stronger axles 4 it and u can race that bitch.

So since I'm gonna replace the rear axle should i go with the 8.8" or the 9"? How much should i expect to pay for those?
I plan on setting this car up for street course racing.

8.8" will be fine. If you plan to run slicks you should consider getting 5-lug axles and rims. Possibly 31 splines also. What trans. will you run? What's the budget and goal?

I'm not running slicks. I plan on putting 4-lug 17"x10" Cobra R wheels. What rubber would you guys suggest. I also want to convert the auto to a Tremec 5spd. Any suggestions?
Please keep in mind that this car will be a road course car.
