I lied. I knew rereading what I wrote was wrong. I put neoprene on top of the sobrothane so it protects the sorbothane.

If you can't find the Sorbothane, one of the guys on here suggested making pads out of the RTV silicone I use for sealing the cylinder head, sorbo pad, and cylinder. Wrap some painter's tape around the cylinder head, stick a rod (plastic or metal) into the nozzle of the head so it just fits snuggly, and fill the backside of the head ( the side with the rubber washer attached) with the RTV, about 3/16" thick, and smooth it down as best as you can. Unfortunately, it takes about a week to fully cure, but it's very durable, and cheap.

This gun is turning out to be a nightmare. I got the AoE corrected but somewhere along the road a few threads stripped. I think this thing is on its last legs. On the plus side, I now feel comfortable in the gearbox. Now I just need to find a new shell.

Oh, and the viton seems to work just fine. Not as quiet as I imagine sorbo would be, but it's as soft as the rubber already on the head.

Don't throw the shell away. Get yourself a helicoil kit and save the threads.

You can also retap the threads to one size larger, I believe the standard thread is M3-.5 or M2-.5, either way, just go with a size bigger then the screws that came out of it.
