I forgot HJ commercials don't have to comply with ADR27, but they got the same engines as the HJ passenger vehicles. Being a 1/75 onwards HJ it will have a 7045281 carby, there is one on Ebay right now. All 308's on HJ and LH from 1/75 through to when the very last HJ's got ADR27A carbies had the same carby, regardless of manual or auto. Problem is on these carbies you are fighting with the Torana w@nkers that think that SLR5000's are more special than they really are and hence buy these and sell them off at a premium as SLR5000 carbies which is partly true, but they also suit all HJ with 308. Most other timeframes had separate carbies for manual and auto but you are lucky in this respect. You might want to find the 4 digit code after this number as you need it to be before 5/76.

The carbs look pretty much like a HQ carby (which carried on into 1974 HJ) except the fuel bowl is sealed. This Ebay auction below has one of each type in it, the LH carby is the sealed fuel bowl type and the RH one is vented - see the metal cover over the vent just to the left of the accelerator pump? The LH one is missing the cover as it isn't needed. These carbs may not be what you want, just show the vent.

Did you figure out if your van was a Sandman or not? I'd given it little chance being a commercial tyred HJ van. Does it have the HJ centre console brackets? These are pretty hard to fake as they are unique to HJ.
