Single Piece Rear Bumper Filler installation on a nice, clean 1987 Buick Grand National December 23, 2013 by webdev 1 Comment Comments tiopupodo.science says February 11, 2016 at 6:40 pm Towards the end of GM’s production run on Buick bumper fillers, the prices were absolutely insane. $850 plus for a pair of rear fillers, $350 plus for the front pair. We started getting these remanufactured and understand the chemicals used to make these went thru the roof. I list some of the differences between our units and the other types.
