The front one has rivet like tabs on the back, you may be able to remove them from the back when the hood is popped, not sure, never tried. PM MadMed with the CF hoods, he has taken his off, and must know how.

On the rear, you are correct, no tabs there, just heat, use some non-wax dental floss or low test fishing line, followed by some 3M wax and adhesive remover, and followup with some proper polishing, if you intend to leave it off....

Hope this helps.
