Try looking at
www.latemodelrestoration.com website. When you go to their home page, look on the left side and find the ChevyTrucks line and click on it. They are good to deal with and have a good selection of parts to restore and/or modify these 88-up trucks. Don't get turned off because they have parts for other vehicles. I'd recommend ordering one of their catalogs....they're color and are good reading. The
www.lmctrucks.com website offers catalogs and the breakdown shown in their illustrations is good reference material. My headlights/parking lights are from CKResto, which is what Late Model Restoration calls their truck parts division. Check 'em out.
As for the smoked parking lights, I haven't seen those. I'm adding a pic of my truck taken a couple years ago. Since then, the bumper has changed to a smooth one and the side trim is gone. Currently, I'm getting the mirrors ready to paint white, like the rest of the body.
Good luck on your project.
