I'm not a big fan of ROTF Bludgeon's head, and it seems like I'm not alone based on the comments I've read. So here are some possible replacements. Chrome Skull Tire Valve Stem Caps Terminator Salvation toys Only possible problem with the tire valve stem caps is that they may not be the right size. Chrome looks cool, but it could always be stripped and painted white as another option. The Terminator Salvation toys come in different size classes, so finding an appropriately sized one shouldn't be a problem. Also these toys should still be available locally, so that's a plus.
