I can get a v-8 8" diff for $100. The problem is that it's from a 67 and I have a 66. The 67 is 1" wider which gives it 1/2" on each side. I'm kind of particular about rims, and when I switch, I want it to look nice. I realize that I will have to add 1/2" to any back spacing on rims I buy, but what I want to know is: Do you think rims will look ok once I get to that much back spacing. I'm only going to run 225s probably at the most, but I want it to look nice, would I be better just gutting my 6 cylinder rear end and having everything replaced? Any help would be greatly appreciated.
