Though I have an original-style seat in my '66 I think your options are numerous. But I wouldn't get too caught up into having to have the seat fit the original mount points. It's not a big deal at all to drill out a couple pair of new holes for new seats. My low powered Makita was able to chew through the old sheet metal in less than 10 seconds when I drilled holes for my new shifter boot. You can either have the original holes welded in or just put the old hardware back as filler placeholders.

Thanks to all for the info! My concern with not using stock mounting points is that just bolting through the sheetmetal doesn't offer much in the way of safety. (I admit I haven't looked at the stock mounting points, which may not have much additional reinforcement compared with just going through the floorpan itself.) Obviously if safety is the ultimate criterion, I should be buying an '04 Silverado instead of this '64 C-10, but I still want to do what I can to keep it safe. And worst case scenario, I could always fabricate my own reinforcement system. Just looking right now for something that could get me by at least temporarily so I could drive the truck while working on it.
Thanks again,
Brent
