67Rocket

I ordered new bumper fillers for my 67 F 85 from OPGI and the rear ones slide right in as they should, the front ones aint no way. My front bumper has two holes (like bolt holes) on each end at the top of the bumper, do the correct bumper fillers have bumps (for lack of a better term) to fit in these holes to hold them in place? The front fillers I received look like they are supposed to slide in just like the rear fillers did. If anyone has pictures of the correct bumper fillers not installed, I would sure appreciate seeing them so I can show OPGI. Thanks.
