Installing a Paxton on my '98 GTS. Manual says to drill 1 1/4" in to the balancer and crank. I have only been able to get 1" in and then it just stops. I guess I am hitting the crank which is harder steel. I have tried different drills at different speeds -with oil, without oil, pushed so hard that I broke a bit, and still can't get in to 1 1/4". Anyone else have an issue? Thanks, Ron.
