I have the same outside c-clip double cardan as shown here. For anyone attempting this in the future, Rockford driveline u-joint part # 2540 fits this application. The box actually says Koyo replacement. I replaced mine a few weeks ago, perfect fit. Spicer 1310's are the recommended replacement but the width of the joint is 3.22", which is too big. Rockford 2540's are 3.18".
