66 Dart GT 13" 5X4.25 want to update?

I spent the last couple of days working on my truck 2500 HD- I found a smoking deal on a set of wheels and tires- 10 miles on the tires and wheels and the guy had them pulled to put a 8 in lift kit and replaced the rims and tires with 22 inch rims and tires- I bought the stuff removed for what It would of cost for one new 18 series E.. Of course I was in the tire and wheel part of Scottsdale.. So I made the rounds- if desert Valley Auto doesn't have any wheels on monday- I decided to take you guys advice-- 14 5x4.5 wheels with 3 to 4" set back.. Ok since you guys have all the experience- I could use some advice-- front hub, rear axles and hubs, brake 5x4.5" What about the drums size? I eventually will change to disc...Let me know what I/m missing.. appreciate the inputs
