Hello!
No luck so far! Now the back rear brake locks and drags the tire.
I went to see a brake guy recommended by a restoration place. SW Brake and Alignment, when I stopped by and spoke to the owner he said he would have to pull out the axle. With my trusty Shop Manual I think he was trying to say he needed to pull out axle shaft. He seemed to think that the problem was in the back, not in the front part with the shoes, springs, wheel cylinders.

The second guy I spoke also thought that it was the back drum also and somehow creating a mud from the fluid. He also said that I would have to purchase a special tool, I think what he was referring to is the special wrench J-2222. It would also require changing the differential fluid. I would need to purchase the seals and gaskets. I called LMC and was 28th in the phone que. Any suggestions on other vendors?
They both sounded like they knew what they were talking about.

Thank you for your time! I am new to this vintage vehicle ownership.
