I ended up just filling it with rtv but now that you bring up removing it, that's what l will do. Then tap and plug. I believe this manifold will be fine but will totally not be surprised if it does not. I don't foresee any problems out of it as the pulley bracket would not fit if it was incompatible. I believe there may be some 2 bolt power steering pump manifolds? This one has three. The factory map will now be plumbed to the lower manifold to read boost, the bypass valve on blower and then to the fuel management computer. I'm still figuring out vacuum though.
