G'day Murray, I think we predominantly had the 216 Chev engine as standard equipment on all Chevrolet 6 cylinder imports. It is a very rugged motor and was an up spec from our many rival manufacturers, especially from the UK. Very few 228 GMC engines here that I have heard of though I may be wrong. The issue with the 6 lug was the same, due to the small number of vehicles imported, it was important to be able to have common parts across the product range to reduce the spare parts inventories of service centres. Considering that at the time, Australia comprised of only 8 capital city centres across a country as big as North America, with a population of less than 18 million. Still only 21 million! Hence the difference on Australian imports. Regarding the offer of assisstance with comparissons of parts , once it returns from the painters, I will take more photos and take you up on your kind offer off help. Regards, Jayde
