Mine is the original with the metal channel.

Seems like it should just gently pry off, but it doesn't.

Thanks

grab with vice grips and pull side ways and peal it off. Sometimes it rusts on so you will have to keep pealing little bits of it

Remove the engine lid first?

Don’t think so, I installed the glass and seal without removing the engine lid.

I can see installing without removing the engine lid, but I can't see a way to get vice grips on the metal part of the old seal without removing the lid.

Tricks?

Try starting it with a putty knife or screwdriver. Watch for flying pieces when you get started pulling with pliers.

I would definitely remove the engine lid!
