My new '70 Charger 500 has factory 14's with all four hubcaps (survivor car)...but it's a 4 wheel manual drum brake car. I'm considering putting on factory-style power front discs. If I do that, will I likely have to change to 15's, or do disc brakes fit inside 14's? The brakes aren't as bad as I expected for normal driving, but there isn't a whole lot of stopping power in reserve if needed...and I really do like the hubcaps, for the survivor factor... I'm not looking at anything like Hotchkiss, or Baer, or Brembo...just the factory-style conversion kits, for safety's sake. I just got the car, and they'll be throwing salt on the roads soon so it'll be in the garage for a few months. Plenty of stuff to do with it before show season!
