Advice needed on removing some Centurion accessaries

I recently bought a 1994.5 Crewcab dually Centurion Conversion. It has stainless grab rails with marker lights installed behind each door. I want to remove both the grab rails and the marker lights. I was quoted $900.00 by a body shop to remove them, weld up the holes and repaint the area. That is a lot of money. I am considering just using bondo and touch up paint in an attemp to do this cheaper but I am worried about the outcome as the truck is in immaculate condion with only 72K miles on it. Has anyone removed grab rails and or marker lights from their truck? How did you do it and what was the outcome like from a cosmetic standpoint?
