I did this google search and came up with quite a bit of info:
LINK to SEARCH It shouldn't be much different from putting a T5 behind a flathead V8 of the same year as your six. On the left of this page in Tech Tips there is a T5 page. The sources there seem to be all GM but the T5 in my son's Studebaker came from a Mustang and has a Ford bolt pattern. Stude used some Ford patterns but I think we had to drill two of the holes, bottom I think. This was 20 years ago. You may have to search for a clutch plate that fits the splines. Good luck, let us know how you make out. Good engine choice!
