Thanks CNC-Dude. What I really mean by "Baseplate" above is an additional spacer (on top of the intake adapter plate). I just was not sure if a little extra lift would be needed for the linkage to clear the underlying intake body or something like that. Again, I am hoping I would not need this.

Good to know that was a 3" breather in Landon's build. It was hard to know from the photo.
