A little heat from a propane torch. (near the area where they press into the airhorn) I wrap electrcal tape around the lower end so not to mar them (probably not necessary). Also, I modified a set of plain old pliers with kind of a groove (used a carbide tool) that will just kinda grab them without mashing them. they pull right out, (kinda scary how easy some of them pull out). still sometimes they still seem to get out of shape a bit so this technique could still use some improvement. Cliff probably has some secret trick......what do they call that...........oh, proprietary.........(hehehehe). just kiddin" Cliff!
