I ran into the same issue with mine. As I can't weld anyways I ended up having them made and welded on. Cutting those as you have noted will probably work but I'd wait until you have the axle mounted up and the tie rod installed. Then you can make sure you have all of the clearances before the mounts are welded on and that the mount allows the cylinder to be as close to horizontal as possible.
Could I just cut the tab at the red line and have them welded like that? View attachment 330558
My TB is in the top hole. I'm running the pretty orange knuckles. Here's the final version of what mine looks like after the last rounds of modifications.
