Hello all. I recently purchased the HL Abrams and was looking for answers. It came with the new Taigen 4:1 steel gearboxes. I was looking at purchasing the metal drive sprockets and metal tracks from hobby summit, but they were made to fit the tamiya king tiger gearboxes. If anyone could tell me if they would fit, it'd be a big help. They are $160, and that's alotta mullah to drop if they don't fit. Thanks in advance.
