John, how much of the steering mechanism do you have ?
do you need the whole entire setup or just the drum ?
This photo is mostly what you need to get going plus the springs and clamps.
Have you ever had cable steer before ?????? Where are you located ?
Marine Engine has the drum for $9.00.
If you need the entire steering rig, you will have to piece it all together
with a part from here and there........... or, pay $252.00 for the complete kit.

Let me know what parts you just can't find - - - I have quite a collection
of cable steer hardware that I have collected over the years.
