There are 3 types of clutch cables used on the vintage Whizzers. The most common is the version used on the "H" , "J" motors, and "300" motors. The most common has fittings [cable ends] soldered on both ends, one to fit the slot in the handle and the other to fit in the clutch arm. The later EZ Glide clutch cable has a bare end to fit a clevis bolt on the EZ Glide arm, however it has the same fitting for the clutch handle. The other of the 3 cables is for the very rare early "H" clutch handle and the fitting is removable [small cylinder with screws in both ends to clamp against cable].
If you were to cut the cable end off a "H", "J" or "300" clutch cable at the clutch arm side it would be the same as the EZ Glide cable.
The EZ Glide clutch system requires an additional cable mounting bracket [#8154] attached to the bottom motor mount, whereas the earlier cable requires a bracket on the seat post down tube [#2960]. Both are called cable anchor brackets.
Have fun,
