Hi. I have a 1991 ford e150 with the extended cargo area. It has 2 captain's seats on swivels behind the front driver and passenger seats. I'd like to replace the captain's chairs with a bench seat and put a 3rd bench seat behind it. What year's seats will fit this van?

I found some rear bench seats with mounting brackets from a '93 e350 club wagon. Will those fit my 91 e150? I expect to have to drill some holes and cut some of the floor carpet.

Thanks.
