Read that wrong lol. Honestly, 99-06 2500 keys should all be the same, if you're paranoid about it, stick within 00-03 keys, but I bet if you cross reference the part numbers over the years they haven't changed.
As far as the rear, a 2" drop shackle and rear block delete should net you ~ 2" of rear drop. Have you been under the truck? Check for that block, and measure it. Should be just about 2"
