Guys, I'm in the process of rebuilding my original spring saddles and would like to know if the outer bushing sleeve was originally bare (like the sheet metal portion of the saddle) or black oxide treated (plated?). If the bushing sleeve was treated, how dark should it be? Can you also verify if the bushing shaft ends (the area that the attaching bolts go through) was black oxide treated also?
Thanks for your input in advance.
Frank
