It’s the same company. I ordered just the manifold for $89 and they mistakenly sent me the $110 manifold/hardware set. If I was not an honest person I would keep the extra goodies for my troubles. The brass washers and acorn nuts looked good at least! The butterfly washers are absolute junk. I have no clue what that piece in the back right of the first pic is for but it’s practically made of tin foil and half the seams aren’t welded together.
