Swapping out the 3sp for an M22 4spd
I took the 67 out yesterday and was showing my son how to pull hole shots. When I heard a loud bang in the rear. I removed the diff cover & found chunks of gears so I'm replacing the open end w/a posi-w/355 gears. While the car is up on the lift I decided to replace the beat 3sp (hated it from the start) w/ Muncie M22 rock crusher. I'll put the 3sp in the crate and save it for I don't know. Should I save the 3sp or trash it??
If Lars is reading what do you think of this setup? 355 posi & Close ratio M22
