Here I have 2 pairs of short arm rest in good driver condition. I don't remember what they came out of or the difference between years of the side profile so they may fit 60-61 as well but not be 100% correct. These both have the ribs on the side. Could probably use a better cleaning or a redye if you are wanting to make them nicer. One set is light blue and the other is more of a turquoise. Both come with 4 mounting screws. I would like $25 a pair plus shipping from Puyallup WA.
