Tim, it's interesting the 2 gaskets at the front and rear of the pan are cork, just like the sides. I see many of the gasket kits they sell today, the sides are still cork, but the front & rear are a black rubber or silicone (those round 180 degree gaskets). You can imagine there is much cork residue left in the recess areas I have to remove before using these new rubber gaskets, any special tools to scrape these out? I've been using a variety of sizes of flat head screw dirvers, they seem to work pretty good but it is slow going.
