Anyone happen to know what the standard harness bolt-in thread is?

7/16th if it is the bit i am think you are talking about.

these bits

the bolt picth is 7/16th, and the spanner needed to undo them is 11/16 spanner i think. well that is what mine are, and most of cars i have taken the seatbelts out are the same.

I got some nice SVA friendly buckles, swivels and bolts off a Ford Ka.

The bolts have the correct 7/16th thread and are marked 8.8 (rear one's arent and are too long so you need two Ka's in the scrappy) they have a torx 45? head as well

From memory 7/16th UNF.
Just ensure the bolts are 8.8 or higher or Mr SVA will fail them.
Also lots on here about what they bolt into/how the mountings should be fixed and height above the seat base.

7/16UNF normally.
Some racing harnesses are 8mm 12.9

It's for making up some inserts, I have the belt pictured on order...

Thanks All

i have those harnesses. i used the original bolts for the top, but i swapped the bottom ones for M10 8.8 bolts as i had some matching bolts and Nyloc Nuts in my box of assorted bolts, where i would have had to go out and buy some nuts if i wanted to keep the original bolts
