I think just about everyone who has taken apart an SWB armrest has broken this piece.... and nothing has been available to replace it.
Fits all 65 to 68 armrests including the 67S version with the chrome bezel.
Pictured left to right is a 1967S, 1965-67 standard, and 1968 armrest(s).
Crappy pics... sorry. I need a photobox.....
$9 incl shipping.
