I have a couple spares of the cable shifter from a late 80's Tercel that a lot of people seem to be using and recommending. On my last visit to the local Pick n Pull I found three so I grabbed them. These are just shifters, cables are readily available from McMaster-Carr or other sources. I'd be willing to obtain the cables to your requirements and send as a single package if that is the way you want to go.
I can take some photo's of the shifters if there is interest.
