My luck has been decent on most things but this truck is a different story. I guess for the insurance to just replace them then. The 1972 settings on RockAuto show these as an additional rust protector type. And from the looks its the ones I have now.

I was hoping for something that the shop manuals showed a step for step for exactly what I have since I have never dealt with brakes before. The 1972 shop manual talks about rubber boots on the pins and such and these just dont have them. If you all know of a reference that may be closer to what I have please pass it along.
