At some point in later 68 Pontiac switched to the plastic filler.
You mean 'late spring of '67'. I think research showed sometime in May. The first few weeks of '67s came with no filler. People thought the bumpers were mounted forward too far, tried adjusting them inwards. To combat this issue, GM came out with the early metal fillers. Those were not well liked, so then they switched to the vinyl. The vinyl fillers then carried forward into the '68 model year.
I used to be indecisive. Now I'm not sure. I feel like I am diagonally parked in a parallel universe. 1968 400 convertible (Scarlet) 1976 T/A - 455 LE (No Burt) 1976 T/A New baby, starting full restoration. 1968 350 - 4 speed 'vert - 400 clone (the Beast!) 1968 350 convertible - Wife's car now- 400 clone (Aleutian Blue) (Blue Angel) 2008 Durango - DD 2008 GXP - New one from NH is AWESOME! 2017 Durango Citadel - Modern is nice!
