Bench Seat

[Buckthetruck]

I have a '65 C-10 step side that I bought as a "prop" for my studio, but am finding that I am going to want to do more than just get it where it needs to be. It has a bench seat from a '67 (Po told me that) and I can get a couple bolt holes lined up, but it is about 5" narrower than what came original. Anyone know where I can get an actual bolt in seat for this year? What years will fit as it should without needing to drill new holes? Is it '62-'65? Anyone have a bench from a '65 that they are wanting to get rid of?

I am new here. I plan to introduce my truck in the next few weeks.
