Haha, that's another site that I was involved in from the beginning...
I should scour that site for useful information to post here.
The man who says something is impossible, is usually interrupted by the man doing it.
Have you ever seen this resource?snap on 001.jpgsnap on 002.jpgsnap on 003.jpg
I have used it to figure out what some memcals came from. Also has a list of the prom updates each year.
Whatever is yours we can use.
Yes I have one. It has been very helpful but using the BCC Find is much easier. Also if you pay the $20 for Cal Data it's easier. But the SnapOn book is more accurate with the recalls and superceeded prom ID BCC codes. Would like to have the newest version on CD or software that came with it!
