1972 1/2 ton 5 to 6 lug conversion rotors

[demian5]

Hi - I have a 70 C10 with drums all around. I can score a set of front 72 spindles, rotors, calipers, master, combo valve, etc... but I want to keep it 6-lug.

Does anyone have a part number for the 6 lug rotors that will bolt right on? I know I can order a set from a place, but, if I can get part numbers for centric or something similar, I won't be so depended upon anyone later when I need to replace them again.

Thanks in advance.
