Drill Guide SD60 to 8 on 6.5

This handy drilling guide is used to mark the hole centers when converting the wheel stub bolt pattern on a Ford Super Duty front axle wheel hubs from 8 bolt on 170mm to 8 bolt on 6.5” bolt circle diameter.

Simply place the drilling guide over the stock wheel studs, then use the small holes & a punch to mark the exact centers of the new 8 bolt on 6.5” b.c.d.   Drill your wheel hubs to your new desired wheel stud size & press into the wheel hub.

No guessing!  Ensure your new wheel stud pattern is concentric to the wheel hub.
