Which running boards will fit my 1951 Panel Truck?

[keithcorcoran]

My running boards at rotted through pretty good.
Going to be hitting a couple of swap meets soon and a salvage yard with a few pickups so before going reproduction, I wanted to see if I could find any original ones.

The issue is that any ones I've seen on pickups look too short and the ones on my truck look like they're 2 pieces with a seam in the middle as opposed to one long running board. Maybe that's just the rotting.

I can just measuring tape mine and any I find for comparison but it would help if there was some sort of cross reference of running boards that will fit.

Thanks.
