Where can it be obtained (other than from a dealer) and at what price?

Thanks for your thoughts.
I can't add much to the rebuild of the motor, but I did replace the rubber seal Rob 930 asked about.

Just like 350HP said, it pulls right out of the channel. Easy job. Reinstall is pretty tough if you don't want to mess with the metal channel the seal rides in.

There's two ways of reinstalling that I considered:

1. Spread the channel open and pinch the new seal in place by crimping the channel closed, little by little as you go around the engine bay. I thought the end result might be a ragged-looking job. So I decided to go with #2.

2. Leave the channel be and simply spray the seal with silicone spray to make sliding the seal into the channel a little easier. Even with the silicone, it was a bit of a struggle. Lots of shoving and inching the seal along. Takes a bit of time and patience. Especially when the seal has to turn the corner(s).

Good luck.

And BTW, nice job keeping this topic alive 350HP! Slowly but surely it's coming together!
