Dale,
There's a 3 page feature on the Lynx Peugeot in SCW's first 'Australian Motor Racing Annual' - this being the one that covers the 1964 Tasman, etc. Potentially it exists in one of the monthly SCW issues also.
Basically it says Bob rebuilt it to the later supercharged, sleeved to under 1500cc, Peugeot 404 (instead of the 403) engine format. "Dissatisfied with the car's output and performance, Holden decided to rebuild it from the tyres up and fit a supercharged engine for more torque and reliability."
Happy to scan for anyone interested - just pm an email address.
