I found a local dealer who has brand new doors for a 1972 pickup truck. I need to know if they can be converted to doors for my 72 K5. It looks like all I would have to do is cut the toprail about 3-4" off of its front angle and remove the rear window rail. But before I decide to purchase these doors I'd like a few opinions concerning this procedure. Any help would be gratly appreciated. Also can anyone point me in the direction of some custom sot top manufacturers. Thanks.
