67/68/69 cuda dilemma
Sell that old stuff to the resto crowd. Theres a guy that restores that stuff on here. These shoulder belts you can take up the slack like a modern shoulder belt, bend and reach forward and the retractor let's you etc.
Them old factory 2 piece double buckle nightmares sucked ***. I had them in a 68 barracuda, 68 charger, and 69 charger in the 80s and 90s in the age before the internet. Had the net been hoppin and boppin back then I woulda had a set of these in each car lol. Back then N.J. required shoulder belt use if the vehicle was equipped, and those things sucked *** really bad. Now for a 100 point resto, well then yeah you put em in with correct date codes etc.
For a driver I recommend these. If your car came with shoulder belts, you only have to add one outboard anchor point on each side on the floor. If it was a lap belt only car, my 67s coat hook hole is almost dead on where my sons 69 has its upper belt anchor point. Weld grade 8 nuts to thick steel squares, fit em in there, and weld in place.
