not familiar with shock hoops, but here's the deal on the 3/4 ton gear. you want to get a 14 bolt full float rear axle and either a dana 44 or 10 bolt front axle from a 3/4 ton truck or burb. you'll know it's a full float rear end b/c it has a hub which sticks through the wheel a few inches and has a bunch of bolts around it. to check the gear ratio, pull the cover, count the teeth on the ring gear and then divide that number by the number of teeth on the pinion. the number you get is your ratio. you want at least 4.10 to run 35's - this is a common gear ratio in 3/4 ton, not too hard to find. 4.56 might do you better, particularly if you are going to go to bigger tires. i think this might be slightly more difficult to find. what tranny/tcase do you have?
