Bolters:
As the owner of a 52-3604 I looked long and hard for a disc brake conversion for her. I coundn't find any. finally I contacted Carmen the owner of Master Power, who said that if I could provide him with the 3/4 ton spindles he could manufacture
a kit to do the conversion. Haven't located a set of spindles to send him and having just completely rebuilt the front suspension, I didn't want to tare mine down again. FYI, Carmen and I didn't discuss price. If enough Stovebolters were interested I am sure the cost of the conversion would be lower.
