Does anyone know where I can get the dash bezel clips for a 98 chevy lumina (works also with monte carlo, jimmy, and camaro clips i believe)

Dealership. They are hella expensive. If you want to pick them up for cheap or even free, visit a pick and pull junkyard. If they charge you a dollar or two to get in the yard, you can knick all the non-electronic bits and peices you can hold in your pocket and they won't care.
