Seat Belt Bolt Thread Size and Pitch

[viperbite]

Does anyone know what the thread pitch is for the bolt that holds the seat belt bracket on the upper b pillar in an s14? it is the same as an s13.

im trying to find the proper tap piece to buy for my friends car. The knucklehead who sold him the car used the wrong threadpitch bolt on the s13 auto belts and stripped the first three threads. so we are trying to repair it.

i know its a 1.25 pitch but im unsure of the type of bolt and the size... its not M10x1.25 and its just slightly smaller than the wheel lug nut threads.

thanks.
