[Go joe go!]

I checked out obsolete-ford-parts and they have a rear throttle arm for the medium riser but not a kit. They did have a kit for 2x4 (high riser, tunnel port, and cammer) part # c5az-9700-lrk. I'm not sure if this would work for my 450's medium riser application. I also couldn't see any tri-unions. Are they called something else? Thanks
