The slots you speak of, you mean the slots in the K member the mount stud attaches to? I thought about that, didn’t get a good look at it but from online info there is a “locating pin” on the mount that aligns with a hole near the slot. That would limit the travel but it’s worth a shot. If it’s that easy I don’t know what more people don’t do that for header clearance at least short term.
And yes, 1.75” primaries. I picked my material first and didn’t pay attention to the primary size. These were the only ones that were both stainless and ceramic (under $500, at least).
