V1 Seat belt bolts

I'm sorry, but I give up. What size and pitch are the NUTS welded into the frame tunnel? I've tried most everything, and I don't want to clean the threads with the wrong tap. Thanks in advance.

To confirm you're talking about the ones the Corbeau harnesses bolt into, should be 7/16-20.

I thought it was Metric but I'm not 100%.

I'm talking about the ones that DF welds inside the center tunnel of the frame. The ones ALL harnesses probably bolt into.

I remember it being standard because Corbeau was supposed to supply bolts with the harnesses but left them out from my order.
