BaT Auction: Modified 1971 Datsun 510 2.3L 5-Speed

This 1971 Datsun 510 is a modified two-door finished in a custom white over a black suede interior and powered by a Rebello Racing 2,360cc inline-four backed by a 5-speed manual gearbox and a limited-slip differential. The seller is an aircraft technician by trade and built the car over a four year period. Work included seam-welding the body tub, shaving the engine bay, and the addition of a custom Mil-Spec wiring harness, a Racepak IQ3 digital dash, 4-point roll bar, 15″ Watanabe wheels, and much more. Upgrades to the suspension from DP Racing and Troy Ermish have been added, as well as 4-wheel Wilwood disc brakes and an aluminum fuel cell. Approximately 500 miles have been added since the build was completed, and this 510 is now being offered with recent records and a clean California title in the seller’s name.

The body shell was placed on a rotisserie for the repair of corrosion, the addition of reinforcements, and seam welding of the tub. A single-stage finish in PPG DeFleet Vanilla Shake was applied, and the glass and trim were reinstalled with new rubber seals. The bumpers are finished in black and the badges are currently removed, and a set of Bluebird tail lamps replace the US-market items.
