Yeah, I did.
It´s no big deal actually. They´re put in place by 4 screws, 2 each. So a screwdriver and you´re set to go at it. They´re easily put back too. The thing about them is that they´re quite large, designated for large mitts....so, good thing is i have a pair of resins too, customized to my size. Anyhoo, The Museum Replicas are nice. Have a good weight and are sharp (or actually "pointy") as hell, but they´re kinda stupidly constructed where the claws are attached to the handpiece....They are really just meant for display. I reckon that, with the new movie alot of new props will see the light of day...My hopes are up for "bone"-claws....would be neat.
