HelloZero Gravity restart for the battery. Pricey but worth it. On the regulators if you need to buy one buy an aftermarket MOSFET version. The battery bracket maybe ebay. Pay attention to the connector from the alternator to the regulator. These need to be clean or the connectors resistance gets too high and they'll melt. On my beltdrives I cut the connector out and attach the wires directly to each other with wire nuts and then shrinkwrap it.
