If its the older style W5x box (ie, it doesn't have an external shifter linkage), then you can use a shifter from Supra, Celica, Corona - in the 1981-1992 range (RWD).
Yeh, I thought that as well. I went to Pick and Payless and got a few different levers out of Celica's and Corona's and the pivot ball seems to be bigger that the one I need. Any ideas?
