contact a few speed shops or racecar shops in you area.... and get a concessions from them...My car goes out next week to get the mini -tubbing done. Anyone know where I can send my rearend to get narrowed? I may also just have someone put the Auburn posi I bought and the 3.73 gears in at the same time if possible just to get it done! Somewhere close to upstate NY would be ideal, but I'll ship it out if I have to! Any ideas?
