Without this chopped up 17mm I’d have no way of securing my seat to my car, as the rear bolts that fasten the seat rails to the floor pan are as close to inaccessible as can be. I’ve tried bolting the seat rails down first, then attaching the seat to the rails, but that’s even worse. Gotta go in as a full unit.
Someone’s coming to look at the Miata today, and it sounds like he’s ready to buy. Fingers crossed!
