I recently picked up a 1973 Precision and everything is original on it, except it is missing the usual pieces like bridge/pick up covers, and tug bar. I don't really want the covers, but since the holes are already in the pickguard for the tug bar, I figured I would install that. I have an factory Fender black plastic one in there for the time being, but just because I know that it is not original, I kinda want one installed from the 70's. I would like the dark maroon one, as it seems that was a distinguishing trait, but my question is, are the bars/rests from the 70's made from something other than plastic? Are they wood or anything? If they are just plastic, I might not bother.
