It most likely is. Won't be an Ambulance with 1950kg GVW. The only other thing it may be but which is very unlikely is a HJ Holden van with option code B30 (comfort package) which gives you carpet and full length headlining, but these are VERY few and far between. I'd be 99% sure it is a Sandman but you can't tell from those ID plates. The only thing that a Sandman will have that the Holden van can't is a console, so if it has factory front and rear console brackets (not welded on afterwards) it will be a Sandman.

Can you post up the VIN? Will be close to 8M70RFJ5144xxJ. It will help me resolve a fair few cars around it. I have one with BODY number 181834-A, and some VIN digits missing so yours will help me nail it down. Plus a few others around it.

181833-A is the Elizabeth, Adelaide body plant body sequence number. The hard trimmed and painted HJ van bodies were shipped to Dandenong and Pagewood for assembly.
