I have a 79 Bronco with a 6" Skyjacker Suspension and 2" body lift. It currently has 36x14.5x15 Swampers on 15x12 AE 589's. What's the biggest tires i can fit without ruining the fenders? I also have some Bushwacker fender flares that need to go on, will that free up some space for larger tires, I don't know if they're cut outs or not. Also, where can I get replacement rubber fender wells? The ones that are in it now are worn out and need to be replaced. Thanks
