Wesco performance seat belts i bought
Here is the template i made off the 1969 notchback i also have, and compared it to the 67 notchback i will mod for shoulder belts. As you can see, the upper mount point on the 69 is very close to the location of the coat hook hole used on the 67. So close in fact, that i will just enlarge that hole and use it as the mounting location. I need to make shoulder belt anchoring nut plates as well, and show them here.
