[TR] Rack & pinion conversions for TR3's???

>because you install a complete new steering column you cannot keep the horn
or indicators in the middle of the steering wheel

You can maintain the center of the steering wheel location for the horn and
have column mounted turn signals by installing a TR4 steering column.  If you
are changing to R&P originality isn't an issue.  The TR4 column with a custom
wheel looks really good.

Best regards,

Tom
