Here is an active sale of car with high arches claiming to be a 1967. I guess AR T252847 has a typo or two in the number, ends in 6 hours currently at $25,100.
Only got to $30k and is now relisted
Recommissioning a moth balled car (1000 miles per year for 53 years).
I have since tried to look at the body number on this car via the poor pictures supplied and the T in AR T252847 could be a 1 making it a AR 1252847 which is a LHD 1970 GTJ with high arches as you would expect for a LHD 1970 GTJ.
If it is a LHD 1970 GTJ, it could have had a Veloce make over at some point in it's life with the 1600 GT Veloce seats, steering wheel, grill and badges. There is no mention of the engine number.
A factory build certificate should help clarify the car's identity along with title documents, engine number. I would recommend an expert viewing to assist in working out the identity of the car, check rear boot channel markings.
A GT Sprint with a GT Veloce make over recently sold for $50k US about 4 months ago in Australia. Make overs of 1300 GTJ and GT Sprint cars made to appear like a GT Veloces did occur in the past, so no surprise these cars will appear on the market for time to time.
