Good advice. I'll definetely get that app too, that'll help. I was going to go with the orginal rear-end as well. Which I thought the prvious owner had, but he actually doesn't. Sounds like I really need to focus on the rear end gear rather than anything else.

If the transmission isn't numbered, maybe I shouldn't waste any $$ trying to get it here. I don't see where it would really add much value to the car.
