I have a pair of used 911 axles with CV's. I got them at a swap meet and they appears to have been in the plastic wrappers for many years. From what I have learned they are Leobro remanufactured. The shafts are 25 spline and the CV's are 100mm. This would mean they are late 1975-1985 911 type CV's. One boot and three bolts are missing. Thes could be used to convert to bigger CV's. Please refer to other threads as to all the parts that are needed. I believe you also need 911 hubs, stub axles and trans axle stubs to make the conversion. Asking $75 plus shipping.
