wheel stud sizes for 98 GT

Anyone know the answer to this??? I am in need of 3" studs up front and I don't know what knurl size I need. I'd prefer to not drill the hub if I don't have to.

bump for a 2000GT, im assuming they are the same sizeas a 98 and need to know the knurl for front/rear as well... I have heard that they are 2 different sizes for front/rear..

Me too Me too!!!!!

.625 knurl worked for me in the rear with no drilling. the front is smaller so I used the 39/64 bit to drill them out and fit the .625 knurl in there. I believe a .618 knurl would fit in the front with no drilling but they are expensive. Overall it was easy to drill out the fronts, just make sure to use the 39/64 bit, a really good CORDED drill, some Rapid-Tap cutting fluid, and take your time drilling (slow and steady gets through those hubs the fastest). The fluid is very important as well to help make sure your bit stays sharp and lubricated, otherwise I guaruntee you will destroy a bit before you finish the first hole... Good luck.
