Hello Mike,
Norm Withers passing marks the end of an era. I remember Hillman Spares in Blackburn very well and it's morphing into Spares galore in Ferntree Gully.
I used to wander around the FTG store searching for a "bargain" and remember all the Ex military Land rover stock lying around. Automotive Surplus in Mitcham was mentioned as purchasing some of Norm's stock when spares Galore ceased trading. Norm's brother Graham was a fixture in the drag racing community and ran a speed shop in Melbourne and Norm's son Jim does the classic car parts stuff as well but I assume you already know all that.
Cheers
Bill
