You surely can get the CR262 'dogleg' Sport box into a bav, but make sure that you get the right differential to go with it. (The ratio that you're looking for is 3.07) Both will bolt into a bav with very_minor mods. I've done it with the help of the FAQ that the senior six registry has posted, and if I can do it, most anyone can. It is a nice mod though most folks these days are going for an overdrive 5spd. Good luck on your search
