Tried to go to the dealer for parts
It is sad but most dealers have just through away all old parts books. I'm parts manager of a 15 yr old dealer with no books and we just bought another dealer that was around since the 30's. Before I got involved someone through out service manuals from the 40' through 90's..I cringed when I found out. I have grabbed all the parts books left. 1964-78. Some odd hardware is still available. Even if parts are canceled having the numbers is great for cross referencing.
