If you come across one, or another 3 speed with the overdrive, let me know. That is what is currently in my 65 and I will probably have to have it rebuilt one of these days. From what I am seeing online, finding the overdrive tailhousing and gears in it is a true pain.Hello from Arizona. I have an 8 cyl 1964 shortbed c10 pickup with a/c 3 speed with overdrive. I'm looking for an online repair manual. Any suggestions on where to find one? Thank you.
