Yeah, go with a t400 and 203 combo... I would go with a round pattern 205 with 32 spline input... That way the 203 shaft can be cut and splined for the 205 and you don't have to worry about a coupler like the 27 splines... Round pattern would come from behind a t400, don't know what years... I know the '88 crew cab had one that came stock in it...
You'll need the adapter for the 205, then source out the aluminum plate...
When you're ready to start working on the plate give me a call and we can go over everything... It'll be a lot easier to explain over the phone with you looking at the pics...
Round patterns are 85 and up I believe.
