Jackshaft

This is a continuation from the other board. I am just going to have a shaft made so I can get my truck going. Thing is I am wondering if there will be any problems running two different size ujoints? Will it mess with the alignment or the rotation of the shaft? It doesn't seem like it would, but before I drop the scratch on the shaft I need to find out. Thanks.

I had two different joints in my truck on a 3.5"o.c. shaft. No vibes or joint failure ever. It outlived two TH350's, two NP200's and the stock r&p.

Thanks, that's what I wanted to hear!

It won't mess with anything. You'll be fine. ;)

Agreed, no problem. They even make conversion joints where the opposed trunions of the same joint are different series'.
