Plowking, Really the only way, is to remove the fender. The emblems were put on the fenders & then installed on the trucks. It has been years since I've had any reason to remove them without the fender, I usually took a putty knife & slid under them & smacked it with a hammer,breaking the studs off & buying a new emblem & putting it on with barrel clips. I do believe the back nuts can be had from the door jamb with the door off if it didn't have the foam seal & I believe we could get the front one on the left side with some tool from under the hood (with allot of swearing) but the right one was a no-go. I hope this helps, it's been about 20 years since I did one that way, so I might be all wet. I would just remove the fender, it's not that hard & less stressful & you will also do a better job painting. Lorne
