Rear Suspension Parts - Finish Questions

Does anyone know what the original finish was on the 4 "U" bolts that hold the leaf springs to the shock plates?
Also the plates themselves that the U bolts pass through. Were these natural, painted, plated?
How about the rear leaf springs? Painted?
What color were the shock absorbers when the cars were new?
Its all for a 1969 Dodge Dart Swinger, 8-3/4 rear.

Thanks for all the help fella's!
