GL1-1 in the VIN means you have a first year GoldWing.
GL1-2 would be a '76, GL1-3 would be a '77, GL1-4 would be a '78, and GL1-41 is a '79.
Engine numbers go the same way, but with an E in them (GL 1E-1 for a '75, and so on)
Engine numbers and VIN numbers don't match numerically. What I mean is if your VIN and engine numbers are the same, then you have a very rare machine.
