Is that a Repco Record ? The Record used the then contemporary (1948-1962) Holden 6 cylinder ‘Grey Motor’ bored to 2360cc. The chassis was of integral construction with a tubular backbone, the steel body was welded to the frame to provide stiffness. Suspension comprised modified Holden components; wishbones, coil springs and telescopic dampers at the front. At the rear a Holden live axle, quarter elliptic leaf springs and telescopic dampers was used. Reference: https://primotipo.com/2015/06/26/repco-record-car-and-repco-hi-power-head/
