Mothers Polish 1959 Chevy Sedan Delivery

An Iconic Family Heirloom

This 1959 Biscayne Sedan Delivery has been in the Mothers family since 1984. You may recognize it from the numerous ads that have featured its flawless sheetmetal and perfectly polished paint or its multiple trips on Power Tour. Its latest build was commissioned by Mothers owner Barbara Holloway in 2014. Barbara worked with Troy and Jack Trepanier at Rad Rides by Troy in selecting the chassis color, drivetrain, and interior—also insisting on the car's nickel trim. It was completed in time for the 2015 Power Tour, where Barbara drove the car with Troy's mother, Judy Trepanier.

Originally a six-cylinder three-on-the-tree, various small-block Chevy engines and automatic transmissions have powered the car over its long career as a Mothers spokesvehicle. It was still using its factory chassis in 2014 when Barbara, longtime friends of the Trepaniers, decided to let Rad Rides take on the most complete makeover in the car's history. Troy told us he was honored to be tasked with the build: "For them to drive past all the shops from California to Illinois was so nice." The car also proved to be in much better shape than most of Rad Rides' projects. While the car had seen numerous shops and builders that improved the car bit by bit along the way, overall, "It was absolutely perfect," Troy said. Although Rad Rides blended several spots, especially on the underside of the car, the PPG paint sprayed by Chris Guinn eight years prior still looked great and the bodywork was left intact.

Rad Rides placed the pristine body on an Art Morrison Chassis with modified rear rails that were kicked up and narrowed for a lower stance and even more tire clearance. The chassis uses a Corvette C6 suspension that ends at one-off Billet Specialties wheels. The Sedan Delivery was one of the last builds that Jack Trepanier worked on before he passed away. It was his insistence that the car deserved a special powertrain that led to the supercharged Lingenfelter LS3. All of the intercooler water lines and the wiring harness were rerouted for cleanliness. It's mated to a Bowler 4L80E transmission that has the brawn to withstand the supercharged torque and the overdrive that helps make the Delivery the perfect Power Tour Long Hauler.
