My rear end is now a jigsaw puzzle and the axles look like they are worn too, so I'm looking for a complete rear end swap but have no idea what will fit my: 1964 GMC 1000 pickup (long bed) 6x5.5 lugs Does anyone have any idea what I should be looking for? I would prefer to find something close to a 308 ratio to give it good manners on the highway, but I'll deal with whatever I can find that will work. I have leaf springs, but don't mind if I find coil over. We'll weld the tabs and make it work. Could I get by with a shorter axle and find some bass ackwards 5 lug to 6 lug adapters that will extend them to the correct length with the wheels on? Since I want it geared tall, could I even use a car rear end? What are my options?
