I am going to try to respond to you all. to Plymouthy Adams the P-6 has never had spreader pins, the shoes go directly into the wheel cylinder. At least as long as I have had it.
To Dodgeb4ya Drums showed no appreciable wear since I last turned them, but I did not arc the shoes to the drum. I may have to pull it apart and check that.
To Desoto1939 yes I have moved the bottom eccentrics, I can actually do that with everything assembled. Loosen the steering arms and the eccentrics can be adjusted. Yes I may need to rent the tool.
