Christian stopped supplying the hinges some time ago. If you approach it kinda slowly it is quite easy to install, using just epoxy like JB weld. Just make sure if you do use hinges to really know the left from the right gauntlet, and install the actuating hinge on the inside seam, towards your body, otherwise the flamethrower gets in the way, and this also keeps the outside edge closer together as that hinge is installed with the hinge seam inside the gauntlet.
