Check out the page: Bushwacker rear flares
It took quite a bit to get the rear flares to fit. They are also pretty small even for out 31" stock wheel well opening.
See how those upper inside corners are down a little. They were not big enough to push up and attach. If you have a bigger well and have made the cuts, I am thinking these might be too small.
I still think that the ford F-150 flares might be an option after seeing them on a Jeep wagoneer. Maybe there is something else that would be closer? Have not looked in a long time.
