    Well, his 205 should be a 10 spline if it is an older truck, and if that is the case then he will need to find a TH400 version 203, 205, or whatever he wants to use for a case.
    Will also need the A/T column if he wants the shifter on the column, and all the linkage pieces to make that work.
    Tranny cooler and lines, probably different drivelines???
    Just a few things off the top of my head.

    You will have to do driveshaft mods anyways switching since the SM465 is shorter than a TH400. So Front will have to be lengthened and rear will have to be shortened. But you might be able to find replacements, in fact I have a TH400/NP205 front shaft I have been trying to get rid of.
