noticed the corner spoiler i took off has a diamond shaped insignia with the letters AOS & what looks like a numerical number 1 under it then it say's LT.3990475. got the pre-delivery sheet & it states options & say's AIR SPOILER. Gutting the interior today to look for a build sheet.

That is the maker of the end cap. They were all made by AO Smith Co. You have the Left hand cap there. The rest is the Part #.
