Sorry for the teaser last night, it was getting late.
So i know you all have probably seen a blown out o-ring but here is my concern...
I can only assume this is the original dominator piece, only markings i can see on it is cast 12-102

The "bottom" boss (for lack of a better term) has a machined "cup" in it but the top is pretty flat. the plastic bushing shoulder doesnt sit flat. is this part upside down? also the pump side pin boss to pin boss measures 5.64" without the bushings and the place diverter boss to boss measures 5.45". is this too much vertical movement?
