40 Ford truck. I am over planning the install of a driver, passenger and baby seat belt in center. I am considering lap belts only because I am not understanding how I could mount any substantial plate on the upper inner cab wall. I would prefer shoulder belts for driver/passenger and lap for center. Anyone have ideas for shoulder mount brackets? What have you used? Also, Am I over thinking this or is it reasonable to tack a nice piece of thick plate on the under side of the cab, then weld a similar plate on to my center section to run a through bolt through for a belt mount?
Shoulder belts-not a problem. I added three levels of adjustment. Here is the build thread on my 40 pickup. http://www.jalopyjournal.com/forum/showthread.php?t=527407
Try this place. They have brackets for shoulder and floor mounting as well as the seat belts. https://www.seatbeltplanet.com/seatbelts-and-accessories/
