When I drilled the hole for the linkage rod I used a stepped drill bit and stopped one step down from what I needed because I used a file the rest of the way so I can press in a door pin bushing after the bracket is painted.
I also drilled the holes to the manifold one step up so there is a slight adjustment of the bracket.
