I am looking at a TH400 w/ TC and its mated to a NP205 w/ slip yoke in the rear out of a 1980 truck. What I want to know is what is the difference between TH400's, I have heard there are some that have a short shaft and some with long or is that the NP205's input shaft? Next question is probably for Shawn since he has done it. What do you have to do to swap out the slip yoke for a fixed and a guesstimate of costs. <font color=red>BigBurb <font color=purple>IF YOU'RE SCARED, SAY YOU'RE SCARED !!
