Steering column lower bearing

My 1964 Dart just has the rubber seal with the hard plastic bushing. Be careful this modification does not make the whole steering column "too perfect", because the lower end of the shaft actually needs a small degree of "wobbliness" to enable the steering flexible coupling to function... The rubber seals have been a bit hard to get hold of until recently (I'm in Australia) and I have seen guys using those universal (stretch-on) CV Joint boots, with the small end stretched over a short piece of electrical PVC conduit, works just fine! Might not win Top Authentic at Pebble Beach...
