Good work on that seal. If you got it right on the first try you're a pretty talented 'bolter!
One of the important steps in preparing for this kind of a chore is to read the service manual. It is full of good pictures. You can find the service manual on the internet, scanned, but if you don't already have one you should buy a paper version. On top of all the obvious benefits, it teaches me the right words for the right parts. It doesn't help so much when talking with Swedish bildårar.
Next time I have a seal to change maybe I'll see if you can help.
