I have been running the Alba LT arms with 17.5” Fox Floats for almost two years now with ZERO issues. Buy them. https://www.instagram.com/p/ByYmnKPBk51/?igshid=hecytpyulm6l
Unfortunately, that’s only what part of the equation. Domes and base gasket can also change compression. You do what you want, but there’s an issue somewhere.
I'm sure it's frowned upon, but I stick a big flat head screw driver between the fingers on the clutch basket down into the inner hub. Then use an impact.
If the clutch is still in, you just need the impact.
