Found one more reason to have one of the factory assembly manuals. When I have approached the parts department at the local dealer trying to find some small part for my '72 they groan and roll their eyes skyward. When I took in list of the part numbers from the manual along with the manual they promptly looked up those numbers and referenced them to new numbers where possible. I think that they were mildy happy that I was buying some of their old inventory. They did not hesitate to order more parts for me. Maybe others will find that this techniques will open a few doors for them.
