One of the nicest things about my '71 is the interior, which is in very good condition. Up until a few days ago the steering wheel was absolutely flawless (if you overlook the dried up rimblow ring). Well, today for the first time I noticed a small hairline crack beginning in the rim. How do I stop this? The car is garaged. Is there anything I can do now to prevent it from getting worse? Yeah, I know. Probably not! MM
