I built this tool to hold the clutch boss in place while i loosen the nut to get it out of the clutch basket.
What i used was 1" wide steel stock and drilled two holes 2.5" apart from each other. I then used 1.5"M10 nuts and bolts that will fit snug enough in the clutch boss teeth that it wont damage them.
If you can see in the pic I have yellow dots showing where the bolts will slide into, it gives you more than enough space for a socket to get the nut out.
