Had a 94 that park brake went out and case said no longer available, had auburn gear hubs, googled them got their number called them described my hubs to them and they sent me the parts for the park brakes, there are two different hubs, one lighter duty than other. Mine had heavy ones on rear, think looking at the outer plate where the button is to unlock motor from hub, one is thicker and flat across middle to where outer bolts fasten outer plate on, lighter one has a slight indention or curve inward from outer bolts to middle. Auburn will tell you how to identify, also helps to run synthetic lube in them. Good luck
