Early 138 Grey Motor Holden aluminium side plate.
It took the team at Aussiespeed® 3 years to get it right and now you can buy a polished alloy Holden grey motor sideplate. The Aussiespeed® AS0101 accepts a standard cork gasket and cork spark plug seals.
The plate is cast from a high grade of alloy and if fitted properly it should not leak. Outer edge and fin tops polished with blasted alloy finish on lower parts of the casting.
