I came across a sheared off bolt head for the rear seat floor mount. I've never had any luck with extractors so I think I'll soak it in PB overnight and take it to the local machine shop to see if they can remove it. I thought about going at it from underneath but it's tucked away between the floor pan and coil spring.

Does anyone know the specs on the rear seat (bracket to floor) bolts? The parts manual says it's an M8 x 1.25 x 35 but it doesn't give the class strength. I can get a package of 5 class 8.8 yellow zinc chromate bolts and a pack of 5 M8 black oxided washers from McMaster Carr for about $9. I don't know if class 8.8 is high enough for this application. Should I go with class 10.9 or 12.9?
