I looked at a late build HQ Ute in Adelaide about 3 years ago which was a late build 8/74 (if I recall correctly) which was a L31, M21 package, 2 seat compliance and Belmont. It was for sale for 7K without the original driveline but had GTS Guards. I was very keen to investigate, test drove it but decided it wasn't genuine because it was Absinth Yellow, r a HJ colour and I thought something was suss. It wasn't till some many months later whilst reading posts here about how Holden often bought in the new colours at model changeover that it most likely was a Sandman or a very strong candidate. Sadly by then I had thrown away the compliance plate details but there is someone here in SA driving a very nice HQ package, maybe not even knowing what they have.
