There is a 1962 falcon in my local P&P. It has spring perches with clips on the ends and look like bronze bushed perches that I have found pictures of. There is a plug in the bottom where I think the zerk should be.....so they never got grease???? The junkyard gods are stingy with these things around here, so I want to get them, but will they be useable without being greased on some kind of interval? They dont look thrashed.
