Wayne/Dan at Brewers can hook you up. It will cost about 1/4 the price to get the parts and rebuild it yourself and there are far fewer parts than you might imagine.

The shift levers in the shifter are probably good but there are wavy shim plates that go in the shifter body that can wear and create some slop. Also, the pin could be worn. For $100 you can get the entire shifter rebuild kit from Brewers. As far as the rods are concerned there are nylon inserts that you can install to take some of that slop out. It is rare that the rods themselves are bad.

Lastly, a majority of my slop was with the operating levers for 1-2 and 3-4 on the transmission itself. Not only that, the shift levers themselves can get their studs rounded off.

Feel free to take some photos and send them to us. Replacing the shifter and rods may not be enough and it could be way too much. For mine, I had to replace the shifter shims, the shifter levers (inside the side cover) and one operating lever.
