X2 atilla, I had/have this problem with mine. My driver's side regulator had a broken plastic tab on the front side and I "rigged" the old plastic window tab onto it for a fix but it's still not perfect. I haven't wanted to shell out the money for a whole new regulator yet as it still works fine just once in awhile it'll lean a bit. Most of the time it goes up and down just fine. I also have the SBC brackets. The previous owner of my truck tried to rig up a solution for the broken plastic window clips and I think messed up the regulator in the process.
