2) That bracket you are working on, note in the kits there is an offset in the bracket which offsets the caliper mounting further inboard a little. Again for wheel clearance.
3) The 5 lug kits have early 70's Camaro components which work with the 15" wheels better.
I appreciate the info. I have 78 k10 rotors mounted on my original hubs(with roller bearing conversion) and 72 c10 calipers and test fitting 15x6 wheel vintiques series 62 with 4" bs. https://www.summitracing.com/parts/wvi-62-5606334

A 15" wheel SHOULD clear. I just need to find the right one or use a larger spacer. I know 3/8" will do it but then that will need longer wheel studs. I'd like to stay at 1/4" or less. I can grind some off the corner of the caliper since it isn't rubbing much. I just have to iron out the bracket issue. I will probably just go ahead and order these https://www.speedwaymotors.com/Weld-...cket,3348.htmland build them the way that they were done in this thread https://67-72chevytrucks.com/vboard/...d.php?t=797504 since this is where I got the rotor and caliper info to begin with.
