THERE ARE NO NOS BUMPER FILLERS OUT THERE. i 'VE LOOKED FOR THE LAST 2 YEARS. I RECENTLY INSTALLED AN AFTER MARKET SET, THAT I PURCHASED FROM COLLECTORS AUTO SUPPLY IN PEACHLAND, BC, CANADA. MY ORIGINAL 1979 PONTIAC GRAND PRIX SJ HAD A 1 PIECE FILLER FOR THE REAR BUMPER. THE AFTERMARKET PIECE COMES IN TWO PIECES. I BONDED THE TWO TOGETHER TO FIT THE ORIGINAL CHROME EDGE TRIM MOULDINGS. THE PLASTIC CHROME TRIM THAT CAME WITH THE KIT WAS CRAP.
IT ALL FITS & LOOKS GOOD. THE ALIGNMENT WITH THE LICENCE IS JUST A LITTLE OFF, BUT ITS HARD TO TELL. THE AFTERMARKET ONES ARE MADE FROM ABS PLASTIC.
I,LL POST A FEW PICTURES SO YOU CAN HAVE A LOOK.
