Looks like that Steele product might need to be used like KSGuy said.. cut and glue... There was a WS seal produced that fit the 38-47 COE correctly. I purchased one from Northern, but Northern is no more. I'd talk to Karl at Wescotts to get the latest skinny. If he doesn't sell it, he sure would know if anyone still does.
Thank gents. I will be following up with tips. I did find a C.O.E. correct seal online at one of the repop dealers back in 2015 when I first bought my rig and I was haunting the websites. Probably Northern. Too bad I didn't order it immediately. I have recently purchased several items for that stage of my build fearing yet more will be discontinued. So I have apparently wasted my coin on the Mac's item... ah well... I'll take a hit and re-list it at a discount on a pickup forum. Too bad the "expert/informed" sales desk help are not "experts". Steele seal seems like it should work... I'll look into that...
