Got the door hinge bushings and pins done:
The roller door positioner is bent, so I ordered a new one. Not sure how it comes out.
So went out to see if I could fit a Sawsall in there to cut the top off the roller pin. Nope, won't fit and my Dremel tool is down in Fullerton, CA. Oh but the newly installed lower bushing of the upper hinge is now broken, so I will have to pull the door anyway. Wondering if the bent roller pin is the cause? Sounds like I'm going to become an expert on this job.
