    Hi, I'm keen to do something like this for a CUCV. The TH400 isn't suitable for highway miles.

    I've seen one write up with my vehicle and a NV4500, but he used an older pre-96 tranny. It all bolted in with just a 2" difference in height over the cross member (fixed with a short piece of 2x2 square tubing bolted in).

    Can you confirm that the older transmissions work just as well? The ratios in the older 96+ version look much more suitable for the 4.56 axles.

    Any gotchas? I read I'll need a different starter (not sure if the 6.2 or 6.5) and maybe use a 6.5 flywheel? Will the bellhousing fit without holes? It looks almost too simple to be true.
