So I have these wheels laying around in my garage. I know nothing when it comes to back spacing or anything like that. My 70 is a 6 lug truck 2wd. These wheels I purchased for my 2011 silverado will they work on my 72?

don't quote me (which I realize renders this input useless...) but I believe the hub diameter is different between the "newer" 6 lug half ton trucks and the "older" 3/4 ton trucks (i.e. the bolt circle is not the issue, it's the hub center opening diameter....) I do know this is the case when comparing 60-66 C10 6 lug wheels and newer 90's ish and up C10 6 lugs - but am only ASSuming this is the same problem for 67-72. So, I'm looking to learn something here as well....

Bueller? Bueller?
