I thought that was odd as well when I first saw it, so that solves the mystery. Now the question is can it be used for a FD if you plug that charge pipe valve? Pretty much it looks like you can just replace the stock one exactly right through.
the hose diameters are different. you can probably rig it though, or just buy the right adapter. $50 shipped.
i would say your best bet would be to either get the greddy elbow which has a flange already on it.
One thing I've never found an answer on is when switching to the Greddy elbow w/ flange, or similar, what are people using to cap the stock mount flange on the y-pipe?
