Thanks, you are correct. I will check on the enamal. Now back to containment seats. When I switched head restraints from a short left to the long one. I threw the old one up on eBay and was surprised at all the Kirkey stuff. Plus my seat tip sold in three days for about 70% of what I paid for it. Pretty good by used race part standards. So back to seats, there may be some usable parts for your base on eBay.
