ROW Car Seatbelt Hardware

[LUFTKUL]

I'm aware that most, if not all of our U.S. bound Porsche air cooled cars are mostly metric except the seatbelt hardware. They are SAE.

What about ROW cars? Are they SAE or Metric for seatbelt hardware?

I'm trying to order new seatbelts and hardware for an '84 ROW 911 that had the original seatbelts and hardware removed long ago for a roll bar and a 5 point harness. That harness is not using any of the factory mounting points.

I don't have physical access to the car for a few weeks or I would go check it on the car.

Any help is most appreciated.

Same SAE hardware the world over.
7/16x20 fine thread SAE

Although, some people make M11x1.25 bolts work, the thread pitch and size is close enough to set several threads in.
