A friend just showed me a 4 speed trans he claims came out of an early 60's Dodge. The front spline has 23 grooves and it rotates freely. He told me that the internals are in very good shape when he checked it out. On the tail shaft there is a raised letter "A" which has a zero in the middle of it and the raised number on the tail is C-85638-K. There is an access panel on the left side that is held on with ten bolts. That's about all I have at the moment. I didn't have a camera with me. Any ideas what this is and if it's worth saving or scraping?
