I have a pair of Cragar S/S rims which are direct drilled for a 5 on 4 3/4 circle using 7/16 studs. I need to drill the studs holes out because I now have 1/2 inch studs and the nuts have a larger OD shank. the shank is .732 and the closest drill is a 47/64th at .734. next is a 3/4 at .750.
my dilemma is this: is .734 to tight or is .750 to loose.
Cragar does not have a phone #, so I cant contact them.
first race is Saturday next. so I need to get this done asap.
thoughts or ideas.
thanks Rod in AZ
