It is a bit of a mystery those HQ's from Pagewood. I've always thought late 1973 and 1974 Pagewood body plant bodies had coloured firewalls, but i've found a few VERY original later 1974 HQ's that have black firewalls. They almost look like the black is painted over gloss. These are definite untouched original cars, even still have chalk marks on the black! Both are Kingswood sedans. I think they are both 7th or 8th month '74. Earlier cars like 1-5th month '74 at least appear to be coloured.
