Harness bracket thread size?

Hi

Does anyone have any idea of the thread in the harness brackets 9holes or whatever) on the Indy chassis. I have bought a 7/16 UNF tap but it seems to be too big?????

Cheers

metric my dear friend, 10mm, everything is metric these days, i'v recently cleaned out the threads on mine after painting

Not mine pal... i tried an M10 bolt and it wobbled like a sausage in an alley way!!! Martin from MK told me it was 7/16ths but he wasn't 100% sure!!!!!

Which is 11.1125mm if you really want to go metric

You may have got a plug tap instead of a taper tap. A taper tap has a reuced dia to allow the thread to be started.
Seatbelt mounts must be a minimum of 7/16 or 11mm for SVA.
