It is a very hard one to pick. I'd say it most likely is, but it still could be an XU4 Holden van. Metallic was available only on Sandman on HX Holden vans and utes, however the only exceptions to this have been Elizabeth builds which is what yours is. Something is wrong with the PSN though as you have it starting with L2 which it cannot for HX. The last L2 PSN's were 2/75 HJ's. Can you PM me the rest of the vehicle's details? I have 1 x other 1918 painted Elizabeth van, it is an 11/76 L31 M21 example. It has 60A trim too.
