steering wheel diameter

was just wondering if any of you are running a smaller dia. steering wheel with a manual steering box, and how is it? was looking to replace my original wheel in my valiant with a smaller unit(13-14"),but i'm thinking that it would be a little tough and would probly have to crank the wheel a bit more from lock to lock.any input would be appreciated. thanks. ps would be running a 185/60/14 tire in front. 8)
