Re: Help Old Falcons
Unleaded XF's (86 onwards) got the side repeater indicators in the wraparound bumper. Of course the fuel filler neck should have the unleaded restrictor.
The Ford number is in the phonebook, its the customer service centre or something like that, a toll free number too!
Look for date stamps on various components, this should give you a rought indication of the manufacture date - components will typically be withing 3 months or less than the build date.
I posted a lead for you in the rare Falcons thread - Wayne Draper.
I'm not sure where you got JGS from, but if its off the ID plate the JG at least brakes down to -
J -country code for Australia
G - Broadmeadows assembly plant
Don't know what S would be as the next 2 digits are numbers and would be something like 23 for Falcon sedan, S could be something for special order though.
A normal number would be something like -
Australia, Broady, Falcon sedan, 1979, Jan then unique number.
