89 Supra Saltare rudder bearings?

Just picked up an '89 Supra Saltare today. Seems in pretty good condition overall. The rudder is loose though. If I grab it I can rock it back and forth a small amount, the bearings are a bit loose but doesn't seem to leak. I'd like to get new bearings and seal for the rudder. A google search doesn't turn up much. Anyone know a source for these parts? Also any input on the procedure to do this job? This is my first inboard. I'm mechanically inclined and have done body work on cars, rebuilt engines and manual transmissions. Seems like it should be a reasonably straightforward job if I can get the parts.
