Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
Fairly sure the 'f' will be the security code, all the lists I've come across say the 9th digit is the security code and the 8th is the engine.X = security code. But I don't know what that means
This is the VIN for my Monaro ... 6G1VX14FX4Lxxxxxx
6G1 Holden, V V2, X CV8, 1 coupe, 4 active seat belts with driver, passenger and side airbags.
F 5.7 Gen III engine, X security code, 4 year 2004, L Elizabeth assembly plant,
......... and now, I can't find where I got that Info.
