Depends what your friend has and what you mean by "Doug Nash" stuff. Nash has made dog-tooth gear sets for production transmissions and also the complete split-case transmission that can be configured for one to five forward speeds. If he has a modified production transmission, then whatever case it is in has the bolt pattern. If he has a split case transmission, the case has been made with standard GM, Ford toploader and Chrysler bolt patterns, and can be equipped with matching front bearing retainers and input shafts for each configuration. So, the question is not how is the Doug Nash transmission manufactured, but what does your friend have?
