IAG Air Oil Separator includes IAG pitch stop mount bracket ($70) if you run a front mount and prefer the center mount location. It was opened and a homemade bracket was made and bolted on in hopes of getting it to work with a RHD sti that’s still TMIC. It wasn’t worth the hassle. It’s unused just opened and out of the box so there may be a scratch from moving.
