Alternative steering wheels?

[FODFARTS@cs.com]

Hey list,
    I was wondering if anybody knows of any steering wheels from any other 
Triumphs or British cars will fit my 64 Spitfire. I autocross it a fair 
amount in the warmer months and have found the rather large wheel to be a bit 
cumbersome. I am looking for something around 14" or maybe 13" but would 
prefer to stay around 14" if possible. I basically need something in fair 
shape but it doesn't need to be show quality, the stock wheel is in great 
shape. Any advice would be great. Thanks.
