I have found many posts on the pin and bushing replacement. I have done them in the past, but it has been 20 years. I also have the spring tool for the lower hinge. Couple questions. 1. the upper pin on the drivers side is in from the bottom to top, does it need reinstalled this way, or can it be put in from top to bottom on the hinge? 2. I do not see any pictures or "how to" on the roller detent pin. does this drive out the same? As you could have figured, the drivers roller is "cocked" and needs replaced.
