58-59 Factory Assembly Manual Supplement?
 

I know the Factory Shop Manual had a supplement to cover the changes made in 58 and 59. The 55-59 Assembly manual I have does not have anything on the fleetside bed or unique front trim in 58-59. Was there assembly supplemental information that is just not being reproduced?

I've never seen one in reproduction. I think the only thing in it would be the fleetbed and a few other minor changes. The did have a 58-9 truck body book.

That is probably what they used. The bed and front clip stuff (and trim) are the only differences I have been able to see.
