A Melbourne build ute 13 chassis numbers before mine though the body number is 64 before. Closest I've seen yet. Similar specs apart from mine being M41/64V.

Cant read the GVW clearly - is that 2400kg? Interesting, country pack (with the tonner rear springs etc)?

Vombil is right about there being a couple of clues on/in the body. Quickest one to verify is the front console mount of these HJ's are different to other models. Being a M21/2 seater, any evidence of a second tall console mount (like the rear mount) ever being there is evidence of previous seat seperator install rather than originally fitted with a console.
