Shabby, I'm on your side. Not fond of the stripes. To me they look like Indian war paint (no offense intended to any Native Americans!) or football anti-glare paint. And I like the cleaner look of the R/T stripeless.

I'm thinking they should just peel off with the help of some low heat and patience. A good liquid/paste wax should clean off any adheisve residue. That is what I used when I removed the "FORD" lettering on the tailgate of my 93 F150 and the "4X4" decals on my 99 F250.
