I?m still going to make a new post on this with all the good stuff from NathanC?s post and then the complete writeup on mine but i figured i?d post my progress here.
So far i?ve got the underdrive mated to the Np231 with shift cable bracket and Atlas twin sticks setup. I?m almost ready to install the t-cases in the truck, all i need is gas for the welder so i can weld up my homebrew SYE. I?m not sure if the Atlas shifters will end up working or not though because they are short throw and i had to modify the shift levers to work with them. The cases are really hard to shift but it might not be so bad once the shifter housing is bolted to the truck, I hope they work out because i really like the shifters. If not maybe Nathan will sell me his shifter, He offered but at the time i was planning on using a D300 t-case so i declined <img src="/forums/images/graemlins/frown.gif" alt="" />

I am behind on this project a couple weeks because the truck had an injector crap out on it so i have to fix that first. Hopefully i?ll be back on track next weekend.
