Replacing tiller joints on AMF TRAC 14

I have a AMF TRAC 14 that I'm having tiller problems with. I was able to get parts from Windrush (parts are no longer available in the states) but am having trouble installing. I'm replacing the tiller joints that must be connected to the springs inside the tiller. Can anyone give advice about the correct procedure to replace the tiller joints.
Wiuld rather be sailing,
