Just bought a '64 C-10 project truck today. Original bench seat is gone and a couple really crappy buckets are floating around in the cab, untethered. I eventually want something more original back in the truck, but I don't plan a date-coded restoration by any means. Anyone know what range of years will bolt directly to the stock mounting points?

And as long as I'm asking about seats, are there any good sources for replacement seats aside from the usual (eBay, the "Swap Meet" here, local salvage yards, etc.)?

Thanks,
Brent
