Thanks for all the replies. My dad is a big Studabaker fan and talking with him found out that I can pick up the relays and even the wiring harness through them. They used the same unit and one of the parts companies still makes the parts.
I have found out that this will not be a direct bolt in. My tranny is 17" long and the new tranny is 21 1/2" long. I will have to cut the drive shaft and I will have to do something with the linkage. The gear in the rear end is a 3.73 so I will be good there.
Thanks,
Mike
