Has anyone added a gas piston for the battery compartment lid on a TR196? I'd like to add one because it's a PITA when you need to do anything in the battery compartment due to having to prop the lid open. Problem is, the type of pistons used in the front hatch compartments won't work because there is not enough room on the edges to attach the brackets that are on that style of piston. Any ideas or suggestions would be greatly appreciated (and pics if you don't mind to share).
