hardy disk

[Compay]

Hello

did anybody use a hardy disk on the cordon axle? would like to know experiences and part numbers. the 319 always runs great no strange noises or tremblings, or whatever you call it. Its more to lengthen the cordon axle because my new motor om604.910 is 3 cm more to the front. So i want to compensate that' for at least 2 cm. The rest is possible to compensate with the 2 parts of the cardan axle that can move a little into each other. Does anybody know what is the minimum connection of the splines that has to be in the moving area?
