I think the ball size is fairly critical but the exact length of the 
shaft is less so.  The problem is that the ball normally breaks off just 
where it joins the stem, and ends up stuck in the panel, so it has to be 
extracted first (I use a small drill followed by an easy-out).

MEK is very commonly used for ABS here (industrially) and works fine for 
me.  It's even pretty good at welding (gluing, in this case, really) ABS 
and PVC together (you need THF for PVC alone).  And getting thin round 
ABS isn't always easy, though some model shops do carry it.  I'd insert 
a bit of aluminium rod, myself, which makes it less likely to happen again.
