Looking at a 70 Chevelle SS. Numbers are suppose to be matching. I have decoded alot on the vehicle but have one in question. I have engine code of T0203CTW. I know what that is but under it and to the right there is the code of 10A133221. I know that the last six digits are the last six of the vin. What is the 10A stand for? What is this code for?
Thanks,
Sheila
