New concours reproduction under-ride traction bars for 64-66 Mustangs are now made by Scott Drake. These are reproductions of the traction bars originally installed on 66 Shelby GT350s by the factory to eliminate axle wrap and wheel hop. They feature authentic details to perfectly match the appearance of the originals. The heavy-wall tubular bars have cast ends with correct ?M-1? markings. The unique 3-bolt cast axle mount brackets have accurate ?10-70? markings just like they did in 1966. The original bars were made from thin wall tubing and are prone to bending. Scott Drake traction bars are made to handle more power with super strong .187 wall tubing that is twice the thickness of the competition. Each kit is finished in a durable semi-gloss black powder coating for a lasting show quality appearance. Rubber bushings, alignment spacers and zinc plated grade 8 hardware are included. Like all Scott Drake products, these are backed by the Scott Drake 100% satisfaction guarantee. Note: Welding required for installation.
