I'm changing my '47 3100 to an open drivetrain. I did some horse trading and have a rear axle from a '58 GMC 1/2 ton. Last night I pulled the brake drums and discovered the parking brake lever that attaches to the cable and parking brake link that fits between the primary and secondary shoes are missing on both sides. I did some searching last night and could not find a source for these parts. Does anyone know of a supplier?
