show-nuff does. Thanks a lot. It will work till I find a bargain deal in the future. If it runs decent with it I may even keep it. It is all purdy and stuff. :p

Ive got a pro products crosswind that I have ran on my camaro in the past. Not the greatest casting in the world, but seemed to perform fine.
