If you are careful and take your time you can repair/restore some pretty big cracks and even out of round wheels. the plastic of the 60's just does not age well and finding one for sale without big ol cracks is pretty rare. I had one of the wood custom wheels and thought I liked it until I got the restored 68 Deluxe wheels in there. http://www3.telus.net/68bird/steering_wheel.htm I have seen the sites of people that make the recast replacements. they are awesome but REALLY expensive.
