You may want to check with Gary Goers, contact info
here. I don't recall for sure, and his latest printed catalog is not complete, but I think he might already make these. If he does not, he may be a more cost-effective partner than one of the larger outfits like Metro or Steele. I have had him make rubber parts for me over the yeras and while there was some waiting involved, the pricing and quality have been top-notch.
