I checked out an RA23 i found in the trader today for $400 negotiable at Mount Barker. It's not in good condition but u may be able to salvage some parts. Crome window trims are good plus rear bumper looked ok. Can't rememeber roof and bonnet but doors and boot were accessible by putting ur hand thru the rust! There were some old school mags too that u might get $50-100 for. It could or could not be what ur after but i thought it was worth a mention.
Cheers, Pomey!
