Is this feasible? It looks as if it the bolt pattern is the same.
Has anyone done this?
What machining is nessary if any?
I thought I would seek knowledge before I rip into it. Is there any out there? | | |

Once you have the OD on the 4-speed you'll have to make your own shifter rods. You can't just order the Saginaw shifter from Patricks as expect it to work out of the box.

It's true. I really don't do anything but browse the Internet looking for trouble... | | |
