The 67 P/S rear support strap was mentioned a few posts back, but all the pics show them installed. I was missing mine (or can't find it) so West Coast Cougars (again) to the rescue. Here is a pic of one out in the wild, chasing salmon running up river.
However, the finish appears to be a zinc phosphate (or parkerizing). You can make out the shiny, worn through area.
Can anyone validate the finish?
