JimG, I have a '66 C10 longbed Fleetside that's all original with only 14000 original miles.It still has the Orig. U.S Royal, bias ply spare tire, & it's mounted in a standing position, inside the bed, up against the (right side) inner bedside. It has a Factory looking stand with a threaded stud for the tire to bolt onto. There's nothing under the bed.
