Hello, so i put my rock-force axles in my wreckluse chassis and bought a comp crawler trans so i have f/r dig and im not thrilled with the losi drive shafts but the problem is the output on the losi trans is 4mm(i believe) and on my axles 6mm(i believe) and there isant much clearance on the transmission end for my rock force u joints (dia. wise). So i figured id ask and see if any one has run into something similar or has a solution for it .I just want some metal u joints that dont snap(5mins into first test run) or make so much noise like the losi's did."thumbsup" any help greatly appreciated i want to get this thing moving im sick of looking at it sit
