Help !!! Wheel lug Q????s

[Spray-Bomb]

Ok heres tha deal

I have a 67 that the PO converted to 5-lug, but when he did he made it 5 x 4 3/4 instead of 5x5

So I want to change that, the rear is no big deal cuz I'll either swap rear ends or axles

But the front is where my questions come in
I found some sweet look'n 6-lug wheels today at a good price, so now I'm think'n bout go'n back to 6-lug

But I still want disc brakes, what do I need to do this

Please steer me in the direction I need to go, thanks Matt
