[QUOTE=SS Shaun;38698]lol until we meet at the light...lol if you are looking to stay original then leave it alone. but richmond makes a trans that is exactly like the M22 but it has 6 gears. no cutting no welding

I am still pretty original and want to keep it that way. However, my brother just had a 454 built up for his 1972 C10 truck. He wanted to put at M22 behind it but he may need to look into something like that, thanks for the link.
