Sorry, please don't think I'm trying to take your thunder. I just thought this would help if this link works. It is someone doing a similar project as your. It has some info on transmissions, and bell housings, if anyone else would want to do something similar. I have a neon and was wanting to build a duster with a 2.4 turbo in it for fuel mileage.
