I have a '96 F-150 with a 302. what I want to do is convert the stock auto hubs to manual locking hubs. I did some research on it from various aftermarket dealers. all say to get a kit in addition to the new hubs. but what sort of kit should I get? also, which hubs is most recommended. Choices I have in mind are Mile Marker and Warn. love my truck, but dont want the hubs to fail when I would really need them to work. Thanks
