Four speed conversion

I did the exact same thing 2 years ago Steve.
I used Jamie for some stuff and pieced a lot of other stuff from several sources.
It’s all basic mechanical and welding. No big deal as it’s all OE architecture and has been figured out for you. Just research and follow how Chrysler set it up.
I used the bushing on my setup as opposed to cutting the input shaft and using a roller bearing (bushings over needle bearings when possible for me).
My crank was drilled from the factory but no finish honed, so I used the undersized OD bushing that was mentioned.
Definitely align the bellhousing as has been said. I used Robbmc offset bushings to dial mine in.
I’d recommend that you take the flywheel and pressure plate in and have it balanced. They are never “zero” balanced from the factory even though they are advertised as such.
I epoxied my hump in as there is no structural component to it (probably just as strong as welding it anyhow)

Here’s a couple pics. Let me know if you get hung up and want specific pics.
Have fun!
