Hi HK1837, Firewall was black and I would be pretty sure it was built at Elizabeth as the local dealer was supplied via Adelaide, I just found an old log book that I used to keep for my cars on trips and the Capri's last entry was 10/74 and the first one for the Kingswood was 12/74 (went down to Adelaide to Suzi Quatro), 8 gallons from Broken Hill to Yunta, (about 125 miles),so I must have been pushing it a bit..lol..Cheers
