I've been seeing reading alot when those who want to put in lg rear wheels you need spacers and "massaging of the fender" not sure what that all means. I mean I understand but not sure how you would go about that I guess... This was a set up I just love.

I have 17" x 8" on all fours with 4.5" offsets. I really dont see how you would get the rears to clear without having a offset of 5.5" to 6". I assume you have drum brakes ?

all things considered, I dont see how you could get by just rolling the lip in the rear quarters. I would almost think you would need to cut out your quarter lip completely and raise it.

the best thing to do is go to a good tire shop ( not a discount tire place). If they know you are serious about buying, they will try slip up to see what interferes and you can see what has to be done.
