My TR6 has the original steering wheel, again a unique part of the 1969 model year. It is (i think) the only year of TR6 that had holes in the spokes. Starting in 1970 the spokes had slots instead, which are apparently less likely to trap your fingers while you're driving.
It's a 15" wheel and thin, which is in keeping for the time, but often replaced with a smaller diameter, thicker wheel more like modern wheels. While I admit that an extra inch or two of leg room under the wheel would be welcome, i like the original too much to replace it.
