yeah, the caliper bracket is what's holding it
it's sandwiched. gotta wiggle them apart or torch or find a spot to hammer sometime in-between to separate, but you might mess something up that way.
I ditched my original sheilds in favor of some nice new ones steel ones...I think all the vendors have the same galvanized set and they look good that way.
Don't have a better pic but can take one if you want one:
I also think I have my '76 stock ones that are painted black--I think I mounted and then it sat and then I removed.
