correct wheel size 66 mustang 5 lug
looks like my family may be buying some new or used 5 lug wheels for my 66 Mustang for my 50th birthday, My son asked me what size is the correct match and he wanted to be sure to buy the correct ones. It looks like I have a 67 -8" inch rear end which may be a little wider than a 66 -8" inch rear end, the lug pattern measures 4.25 " inches but I have read that the correct pattern is 4.5 " inches? what is the correct pattern and backspacing for 14, 15, inch wheels? any other tips or info would also be helpful.
