If there were any Holden diesel Bedfords, I would imagine that they could have used Hercules engines. These were fitted to Chevrolet, GMC and Oldsmobile export trucks. This was easily done as all shared the same basic chassis frame and Olds were a direct GMC clone, and in the case of the COE trucks, all were based on the same components. However, what other diesels were imported at the time? Did Petter, Dorman and other British makes come over?

I remembered that in 1939 someone re-engined a 1937 Buick with a diesel engine in the UK. I gather that it was not unknown.
