Maddoggee1959 - Not sure if it may be of some help, but many Bolters have purchased and installed 3-point seat belts from Juliano's Hot Rod Parts to upgrade their rides for safety.

Here's a link to Juliano's 3-point seatbelt install in a 1956 Chevy TF Truck that might prove helpful with your question. Not sure if a TF Burb or Panel has the same way to reach up and inside the cab space to install the anchor plate as the truck in the instructions, but maybe a source for further ideas to get there. wink

Let us know what you end up doing as it could help other Bolters in the future. smile
