The 15" diameter steering wheel on my BN7 (1960) is becoming too incumbering for me to fit in the seat. (Yea, I know lose some weight! But being senior Healey driver, that ain't an option). I am looking for a 13" or 14" diameter wheel. My steering column is the adjustable style. There are 6 mounting screws. The original wheel is gone. The present wheel is a Moss (came with car). The key would be a wheel with a center hub opening sufficient for the horn / trafficator module to fit. Any leads/recommendations would be helpful...
