My 1600 only has the Chassis number stamped on the fire wall. Its the only number I can find. I don't have any of the
ID plates they were lost by the previous owner.I rang the RTA and they said I only need the Chassis number to re-register. I know mine is a 69 model and manual but that's all I know haha. On my 71 model the number is stamped on the strut tower so maybe it also has to do with the year models?

Cheers,

Richard
