So I just finished the conversion on my 1st gen 2WD, Cummins. I did a write up on dieseltruckresource.com so I'll just link it here.

I did not go too in depth on the conversion or how to take your trans apart because that info is available on DTR as well as youtube and other places. I just laid out the parts you need to convert the trans and what I spent as an alternative to the expensive 47RH.

Here's the link if you're interested.
