Vin deciphering

[Guest]

I have a 1981, i think, gs 450 T, in an attempt to correctly identify the year i have resorted to on-line vin decoding, which has resulted in zero, the frame number starts gs 400, and it's a 450, however the engine number starts gs 450; i had a 450 before and i obtained the vin information without any undue issues at all. Am i missing something, is there a secret held dear to some one somewhere. Any help will be much appreciated
