My Herald has not reinforcement at the seat belt bolt points.
I am guessing the belts were added sometime after they became available, and the bolts at the shoulder just thread into the B pillar top,
and the rear belt shoulder point is just bolted through the parcel shelf with a nut.
The bolts in the floor also had nothing.
My question is, how do I get reinforcement in behind the upper section B pillars for the front seat belt system.
