1966 Shoulder Belts

68 and up models were designed with rear shoulder belts in mind. The sheetmetal in the package tray is reinforced with a large threaded metal plate as a backing. Although the package tray in the early cars is thinner in the area intended for shoulder belts, It wouldn't be to hard to duplicate or even graft in a section of the later package tray.

I did this (front and rear) on my '66. Here is the thread:

If your cowl tag has a little round hole punched in it near the bottom edge, that indicates your car's production was late enough in '66 to have the factory front shoulder harness mount (see pic above) in the roof line. Makes this conversion EASY.
Regarding the rear, DO NOT just drill holes in the package tray...it is too weak to hold a belt in the event of an accident. I used these (see below). They are expensive, but come with custom reinforcement brackets that mount to existing holes in the trunk subframe and make this conversion safe. Last thing you want to cheap out on, in my opinion, are seatbelts!
Converted all 4 seats to 3 point belts in an afternoon. Made it possible for my son to ride in the car with me...money well spent!
Shoulder belt mount adapter??
Months ago I found out my '66 has the factory installed shoulder belt mounts in the roof frame (awesome). I bought a seatbelt kit before I realized the shoulder mount point is a 2-bolt mount and the belts I have are a 1 bolt kit. I waited too long to return these, so I'm wondering if there...

But that’s only for hardtop cars, right? I have a post car. Built December 1965. I looked at the cowl tag right away when purchasing and unfortunately, no hole.I did this (front and rear) on my '66. Here is the thread:
