Plenty of "gun metal" colored spray cans on the shelf of your local auto parts store. You'll want to paint the pizza pans with something otherwise they will rust quickly. Black might blend in well considering you are running on black steelies already. Plasti-dip also makes a 2 different shades of grey that might fit the look you are going for.

Older S10s had optional manual steering, pretty sure the front ends are still the same on the newer ones. You could grab a steering box and idler out of a JY and swap in manual steering in no time. With how light the engine/truck is, you probably won't notice much more steering effort at all.
