Do you have the CTCI Restoration and Specifications Manual Complete Set #110-58FC?
It is located here:
Gil is the one who put this together.
Especially good for details on Concourse Restorations and want to know everything even the color of washers and bolts.
I just was relocated to another base and mine is packed away but I will dig it out and see if I can find something for you in the next day or two if you don't get an answer elsewhere.
I just found Gil's site. You can contact him there.
