Here is how I fixed it in my '84
1. Ham-fisted car "mechanic" broke the front shifter plastic base ball socket thingy. I cleaned his grease from my Westy and replaced the ball and socket assembly.
2. Pulled the plastic tube couplers from horn joints. They had too much play so I sanded them down a tiny bit and installed stainless washers at ends for very snug fit.
3. Replaced shaft bushings with delrin bushings. They need a regular lube, but are fantastic.
4. Rear ball and socket replaced with a GoWesty cu$tom unit.
The results were synergistic.
Chris.
