Here is a list of codes for the Galants. (thanks to C_Fernance)
For the chassis number eg. GD3-M-41
1st letter - L = Lancer, G = Galant
2nd letter - Series - A, B, C or D
number - 1 = 1400 manual, 2 = 1400 auto, 3 = 1600 manual, 4 = 1600 auto.
3rd letter - price class - M = medium, H = high, P = premium.
Last 2 numbers - Body type - 21 = 2 door sedan, 23 = 2 door hardtop, 41 = 4 door sedan, 45 = station wagon.
So for the chassis number above the car would be a GD Galant sedan, with a 1600, manual gearbox, and the lower spec trim level.
For the option codes.
