Ummm, I had 60 of them Mfg’d , I sold them for $650ea, ive got one left...if you think they are easy to make, have at it.
its not just a round tube, it’s got a specific crush that requires a specific die And at the same time not crush the remaining 6 or so inches of the round end of the tube. Then there is the skin, that an entirely different conversation.
What you have is what GovPlanet stuck in there for next to nothing, it’s worthless because without the crush and skin, you have no place for the hatch seal to seal out the elements.
My units are So good, that once painted and set along side an OEM unit, it’s impossible to tell them apart.
the current eBay units have had some serious complaints of not fitting right and require cutting and grindin.
