The Need for a Lug Conversion

When updating an early truck to five-lug disc brakes up front, the six-lug rear bolt pattern should be changed to match, as this directly affects the wheel selection and fitment for the truck. Many wheel manufacturers offer three times as many five-lug wheels as six-lug. They look better, and the available styles and offsets are generally more accommodating for slammed pickups.

Converting an Old International Truck

We recently converted an old International, a truck we affectionately think of as farm fodder. We updated the truck with a Fat Man Fabrications Mustang II with a five-on-five pattern, but we still needed to match up the rears.

Choosing the Right Parts

We called the folks at Classic Performance Products in Anaheim, California. Since we have a ’65 Chevy frame hiding under our ’47 body, they had just what we needed. The ’64-’65 Chevrolet axle conversion kit comes complete with everything needed to swap your axles to a five-on-five pattern, including a brand-new set of axles, drums, wheel studs, and a rear differential gasket. The kit includes everything to complete the installation except two quarts of gear fluid.

Step-by-Step Guide

In just a few hours and with a 50-pound bag of Oil-Dri, we had the rear completed. Should you face a similar problem, check out the highlights of our swap.
