I hav had a set of metal arms and axles for my tiger for a wile and just tried to install them well nothing fit. The arms set to deep in the hull and the head or the screw was to big the axles are to short and thin and the inner hubs to deep. The good side it after cutting, turning, filing and adding brass bushings glued in the hubs it works better than the others i have done. The suspension stops are brass tube glued in the existing holes it the hull and it sets about 1/4 inch taller than before. Does any one know what these parts are ment to fit because they dont fit any hl tiger i have had.
