Newer truck parts?

[badform]

Hey gang!

First, because we all love pics...



That's from towing my truck home a few weeks ago. Good stuff.


Anyway, I was at the local pick-n-pull yesterday, looking for a mirror for my friend's Golf (no luck there), and while I was there, I scored a nice overflow bottle from an early/mid 90s Silverado (350 TBI). I noticed that the radiator in there was HUGE, and wondered if anyone had put one into our trucks.

Aside from the want to get the engine to build a nice roller motor out of, are there any other parts which work well for our trucks? Obviously the transmission, but what about sway bars and other suspension? Anything else? There's a lot of those trucks in the lots, and never anything much older (though there was, inexplicably, a rusty mid-60s C10 there).

Any other vehicles with easy swap/upgrade options to keep an eye out for?
