4 speed Transmission interchange?
I have a Creeper gear transmission in my 67 C15 . I would like to swap that out with a Saginaw 4 speed. Can I just swap these out and keep the bellhousing,clutch assembly intact. Or is the splines different on the Saginaw?

I am 98% sure the splines are the same.

Spline should be the same but the trans input bearing housing diameter might be different.
Info in here. https://www.streetmusclemag.com/tech...t-bellhousing/ |
