Might try this. The moldings are pretty much the same just different length.
The F-series clips are 3.71" and 3.61" long, the EB clips are 2.38", so I do not think they will work since you would have to cut off one or both ends with the nubs that help secure the molding. You would also cut into or cut off the stock holes, but I guess you could mount them with one fastener in the center like the EB clips used.
However, with that said, the EB clips I have almost seem too short since they barely engage the rocker trim?
I do not have and have never looked closely at any F-series rocker trim to compare the cross sections dimensions to the EB trim, but it seems that it must be wider?
Also, Tasker tells me the above listed EB clip PN is for the center 5 locations and there is another clip used at each end of the EB. I have to dig around to see if I might have a used one to see what they look like.
It's been 10+ years since I removed any original rocker trim, so I can not recall what they were like.
