I had to use a 3/4" ball joint separator to get it out. Stuck in there good. I now see, in addition to the 128551 code, the Bendix stamp and the code 7A19A. Kind of surprising given the Shelby build date of 1/27/67. I think the code means 1967, January 19th? Not sure of second A. Maybe shift? The cylinder retains the black paint on the upper half of the cylinder. None on lower half facing road, but no rust at all. Clean, rust free shiny ram.
