dublenaught,

You are right...as long as you have plenty of room to rotate the distributor, the tooth fairy doesn't give a hoot!

The problem is that external things sometimes complicate matters. If you twist it too much, the vacuum advance might be a bear to connect, or you might have plug wires that ends up stretched to the max. Other than these concerns, ' one tooth off' is only relative to where the distributor comfortably fits.

If push comes to shove on the rotation limits of the distributor, you can pull the plug wires and parade them in the direction needed, and presto, your one tooth off has vaporized.

Pulling the distributor, flopping a tooth and reinstalling it is VERY straightforward..no black magic involved, so don't freak yourself out. Good luck!
