Start with the right bolt circle.
Choose the starting pattern and the target pattern. Motobilt drill guides locate hole centers for specific hub conversions or a spare-tire-carrier conversion. They are not wheel adapters or complete conversion kits.

Bolt-Pattern Drill Guides FAQ
What does a Motobilt bolt-pattern drill guide do?
The guide locates the new hole centers from the existing bolt pattern. The installer uses those marks when drilling the compatible hub or carrier. It does not act as a wheel spacer or bolt-on wheel adapter.
Does the direction of the conversion matter?
Yes. The starting pattern and target pattern both matter. The Super Duty 8×170 mm to 8×6.5-inch guide and the Chevy Dana 60 8×6.5-inch to 8×170 mm guide are separate products for the applications named on their pages.
Can I use the 5×5.5 to 8×170 guide on a wheel hub?
That product is described for a Classic Bronco spare-tire carrier, not a wheel-hub conversion. Use it only for the stated carrier application. Choose one of the hub-specific guides when working on the compatible Dana 60 hubs.
Does the Super Duty six-lug conversion require more than drilling?
Yes. The SD60 to 6×5.5-inch product description states that the hub diameter must also be machined for the smaller pattern. The guide is not a substitute for planning that machining work with your installer.
Are replacement studs and drilling equipment included?
These products are guides. Plan the required drilling, machining and replacement studs separately. The final hole size depends on the studs and application; follow the product directions and have a qualified installer verify the finished work.
What should I confirm before ordering a drill guide?
Confirm whether you are modifying a hub or a spare carrier, the donor hub application, the current bolt circle and the desired bolt circle. Also verify the rest of the conversion, including stud, wheel and hub clearance, before drilling.
