This by no means written in stone...it is from what i have dug up so far in my research and my deductions from my own rigs. Please email me if you have any additions or changes i should know about. I hope this will benifit some of you. Decoding my VIN drove me nuts when i first started, hopefully i can save some people the hassle. Justin
