Again, as I remember, there was a tech bulletin on this subject. I will try 
 to locate it but it will take some time to do so because of my current 
work  load. I believe that one sealing change was done for 1966 as the proving 
grounds  report had a favorable statement concerning all the rust on the oil 
pan as being  a sure sign of no oil leaks for that year.

Yes, I  have noticed this also in my stock of used pans.

What years are  which?
