Hi, my name is Julian. I have a 1967 Mustang 6cyl. I still have the stock 4 lug rear end and i have adaptors to put 5 lug rims. I want to lose the adaptors and switch the whole set up to 5 lug axels. Is this possible without switching the entire rear end?
If so, how would i do it?
And if it turns out that i do have to switch the whole rear end, what would be the best to switch to?

Thanks
Julian
