I just realized I miss wrote that surprised no one caught that till now... what I was trying to say is if you wanted the 6 lug for pattern use the stock 91 silverado rotor. They are not the 3/4 ton as those are all 8 lug. '72 was a 5 lug setup 1/2 ton and 8 lug 3/4 ton. if your going to use a 6 bolt rim and tire on anything using the HD spindle that is when you can use that rotor. If i confused you more let me know I can try to reword it again.
