Couple questions...please anyone. I would like to change out to the 14ff from my current 12bolt rear diff. Problem is I want to keep my high $$ investment in rims on the truck. So I was considering wheel adaptors to change the bolt pattern, 6 to 8 lug. ?? has anyone run wheel adaptors and are the safe ? ?? do I have to change the front diff out for a dana 60 or is it real bad to leave the 10bolt in ? Thank you in advance.
