Yes, I did see that option, but decided against it. I was worried about finding a good replacement nut/bolt combo that was of the proper strength, like a tempered one (this is a seatbelt attachment point, after all). Probably wouldn't have been a factor, but I'm a worry-wart.

Plus I didn't even know if the new seats were even going to work, so even though swapping the seat rails was more labor, I saw it as a guarantee that I could reverse things to their original, pristine, factory condition without making any permanent modifications...

If I was doing it again? I might just drill out the rivet as you suggest, though.
