Crazy Al's right about limited options on improving your rear gears. Randy's Ring & Pinion
www.ring-pinion.com makes a set of 3.90 gears, but your pockets will be empty
. The best way to regear a 3/4 ton is to get a 14 bolt from salvage. Full floaters are readily available with 3.73 gears, a local yard told me that you can now get 3.42 gears, too. Someone else here said the 3.42 are only semi-floaters, so I'm not sure.
