I've read this thread with interest (tounge in check)is this ute a hq because of chassis and a sandman because of Belmont 18v
If I was doing a restoration I would change to HZ chassis because of rts and probably look for one without no's on rail and legally re-stamp with original no's or a police no. At the worst .but if the non matching no's don't worry you register it and drive it
I think
The sale value would be in HZ matching no's sandman
And secondly HZ sandman with police no chassis
