Recently picked up a 57 Panel that we are trying to bring back to life. Someone along the way put a set of early GM car buckets in the 57 that just won't do. I'd love to have an original(s),but I'd bet they are scarce as hen's teeth. Did the 55-59 Panels have the 3/4 bench with a jump seat or did they have one or two bucket(s)? What non-original seats would you guys recommend? I like the idea of the passenger seat flipping up to allow access to the back of the truck. I know this subject has probably been discussed,but I didn't have any luck with a search. Thanks
