I did some research and come up with very little. I have a 73 Astre gt tag i would like decoded.
GT 73 7HV77 ST are the first few characters. So i see it as " GT , 1973, the next number is 7 and a very clear 7 but Astre is supposed to be 2, then H is for astre and v is vega then st i couldn't find anything with st. Does anyone else know what this could mean?
