Just scored another spun aluminun 8' dish, not in as good of condition as I 1st thought, has a bad mounting of 4 bolts which caused fatigue cracks at each bolt, will have to take it to a welding shop for repair. It has a HUGE Hammerblow actuator on it that runs fine, but the boot is weathered and destroyed. I'm surprised it still runs after all those years of leakage. Tried to find Hammerblow on the internet, but they might be out of business. Does anyone know of a supply house that sells a universal boot? It extends about 20" and has a 2" opening on 1 end and 1 3/4 opening on the other. Any help is appreciated as always.
