Wheel/tire fitment 63 C10 6-lug

[63C10StepBigWindow]

Okay, here's my second thread, and I am know I'm being lazy.

I need advice for my 63 C10 re: wheels and tires.

I've been searching for wheels, and I've learned how limited the choices are. I'd like to add disc up front. Is it necessary to convert to 5-lug wheels?

If I keep the 6-lug wheels, where can I find some wheel choices? What can I fit? I was looking for 16s or 17s, but I have no idea what width or backspacing will work. What backspacing will I need with my drums? With discs? I want to do a static drop of 2-3 inches, maybe a bit more. Please help!

As far as my taste in wheels goes, I don't want something too traditional, but I will go with a variation of the Chevy rally if all else fails. If I'm persuaded to go the 5-lug route, I'll be open to all sorts of ideas.
