SHAKER Warm Air Door/Adapter Ring Seal?

Does anyone know where to get the seal for the SHAKER warm air door/adapter ring (see photos)? I think I found it on Year One's site, but doses anyone sell this seal? Thanks.

No one can help?

Try DMT Detroit Muscle Technology - a sponsor here - I'm sure Jim makes one.

I think they are "lorettafillmore" or similar on eBay.

YO was where I got mine years ago, nobody else had it that I know of at the time, did you look at Dales or Dante's? Jim at DMT might have?

I spoke to Jim at Garlits in November. He does not have any. He asked me to send him my original and he could make them.
