Hello guys!
I have welded in upper seat belt fasteners in the B-column in my 67 like the LWB cars. Threaded plate from Lloyd. But which size is the threads? It is smaller than the usual threads and a bit bigger than standard 8mm bolt. Are the bolts higher strenght than normal bolts (8.8)?

I believe all seat belt bolts in all cars are 7/16-20
looking for 1972 911t motor XR584, S/N 6121622
Correct, as far as it goes. SAE 7/16-20 is also virtually interchangeable with M11x1.25, which may be easier to find in many parts of the world.Originally Posted by blucille

Thanks for your answer! Are you sure the B-post threads on LWB cars also are as large as 7/16? I have a 71 tub which have smaller hole, but will double check!
Also, anyone know of a good type/supplyer of automatic 3-point belts which look ok and has a direct fit in a late SWB car (with added B-post point)?

All bolts in Porsches are metric.
Never imperial.
My early '72 is 7/16-20.
Except early seat belt fasteners. US DOT mandated that size and thread. All cars that were ever intended to be sold in the US had 7/16-20.
