i have done some playing around and as of last night i think i am going to abort, attaching this thing to a 12v manifold is going to take a special adapter, both flanges are set up to have studs and have blind holes in the same location so a bolt from the back side is not a option, i cut out a pair of flanges to make a 1" spacer to bolt between the two but the bolt circle is not far enough away from the hole to clear the studs when you wall it up, i think it can be done but not sure it is worth the effort
i have not totally decided the fate of the he351, not sure if i am going to sell it (in a flooded market) or build a manifold for it and bolt it onto my old 6 series bmw

if someone wants it i may sell it for what i have in it plus shipping
