Does anyone know how they go on an Avalanche? I know the ones i had on my Silverado, the ones for the marker lights just pushed on over the light and were held in place by the tightness. The ones for the headlights, i actually had to pull up the hood, the bottom tab went between the bottom of the headlight and the top of the marker light, the top had a tab that clipped on the headlight body and was also held on when you closed the hood. My Avalanche doesn't look like theres enough room for either. Please let me know as i'd like to get some but wanna make sure how they go on before i purchase them. Thanx, Jim
