This is an interesting topic for those of us that were fortunate enough to wind up with the 74s.
I've located an early 74 with a good set of doors complete with regulators and glass.
I'll be able to inform as to the fit on my late 74 soon.
I see where you were coming from, though, Pop.
As far as the XTs go... they are ugly as sin, but they are an engineering masterpiece. 0.29 drag coefficient, AWD, handle amazingly.

I covetith thy Z. Just changed the color to see what the dirty old rat might look like with the same mods you've done. I hope that you don't take offense, if so, my apologies.
