I am pretty much finished up putting the belts in.
I had to fab up brackets for the lower rear mounts.
They fit nice and snug into the corners, and I recessed the nut
into the body of the car. I epoxied the hell out of them with
por 15 epoxy and then screwed them in with the biggest sheet
metal screws I could. Now I know welding them in would have been
a much better alternative, but as you can see I am fairly far along in the
restoration process. I am quite confident they won't be coming out on their own, and let's face it they are a novelty item at best. If I get in an accident that is severe enough to rip them free than I don't want to survive it anyway!
All that's left is to mount the center hook on the tunnel. Here's a link to some photos of the finished project.
