GM truck 12 bolt. any lockers for these?

ok so i have 4.11:1 gears i have now comfirmed, with me and some one else spinning my hubs the same direction at the same speed and the pinion did 4 fast revolutios, while we did 1 slow turn on the hubs. its open differental. id like to change that, ive looked at power trax richmond loc rite set ups, and they only carry the cars 12 bolt version. It looks nothing like GMs pick up 12 bolt... does anyone else carry this without having to buy there whole differental package?
