Long time lurker, first time posting. I am looking at a 2002 Ford E150 ,That is out of state. It has Buckets in the first row of passenger seats and a bench seat for the second row. Does anybody know if they are interchangeable ? Are all the mounting holes the same? Would I be able to put the bench where the buckets are ? The reason I would want to switch is I don't think I would be able to slide surfboards under the buckets.
