GM Seat Solutions. Some GM vehicles (my truck included) have problems where the stem of the seat adjustment handle breaks off. While I don't recline my seat all that much it's sometimes nice to have, so I ordered a set of these replacement handles, they have a longer throat so they should fit on even if the stem broke off. I'm going to have to do some adjustment on the jagged edge with a file and maybe a hack-saw (it broke in a pretty harsh angle.)
