Hi I had a chance to check my mates 8/74 Melbourne built 74 ute, it has black over the original body colour. I am a little confused with the reference to pagewood or were the Melbourne bodies built there ? Sorry for my ignorance.
We pulled the heater box back on this 8/74 ute and it was white behind the cover. The body i am using also has a coloured firewall but it's a 4/74. I am leaning towards painting mine in the body colour, but these are the kind of things i would like to get right.

Cheers Vic
