I agree with this - mine are 1/32" larger then my fittings which are Billet Specialties. Cances are that you can't drill the hole straight and this allows a bit of slop. I also put a SS flat washer under each side for just a bit more bearing area and so it wouldn't dig up the paint, now powder coat. You can just barely see that washer on my front end photo above.
