Hey'all. New 2002 owner here and I'm just getting acquainted with my new-to-me '76. She's been partially restored, some things done better than others. I'm trying to figure out what these seats are from and why they aren't bolted to the floor properly. I know they've been re-upholstered but I'm not sure if they were originally from a 2002. Also, how were the original seats bolted to the floor? I've looked at a parts fiche, but having trouble visualizing.
Would like to do some research before I go ripping up carpet and drilling holes to fix them.
