Steering wheel bolt size??? M5 OR M6?

[Dan@M.A.D]

Just need confirmation on the size of the bolts that are used when bolting an aftermarket steering wheel (Such as a Sabelt) to a hub..

​Is it M5 OR M6?

I was always told M6, went to fit them and didn't fit! So M5

I was about to ask this same question. Anyone know what lenghts ideal for an OMP boss?
