Just got here, have been wandering about for more than 39 years alone. Eureka! seems that the best doucmentation comes from this CRG site and thanks for all the help that has been spread about from the enthusiastic minded Camaro folks and the CRG. I have some questions I will ask later about some potential errors or just typos in some of the decoding that is posted, maybe just typos and of course I have been prone to dyslexia. And because I started out in the orphanage, I am on the hunt for engine block TO921MN, she has a nesting spot being taken up by a step sister with the same DNA. Will give history in another post later.
