Burt,
Rebuilding the 3-speed column linkage isn't that bad. There is a line-up hole that you put a pin through to get everything right on the column. I used Snapper Lawn Mower front steering and spindle bushings and they worked fine with a little trimming. Snapper also has a little bushing that I was able to use on the arms after drilling them out a little. Any manual on your truck will probably cover the process. The main idea is to get the "slop" out of the linkage.
I know this isn't what you had in mind, but half a day and about $10 beats another transmission in my book.
best wishes,
Les
