Dave,

If you use a non-standard method of connection, that provides difficulty 
if you ever have it serviced.  I routinely swap out full options when 
doing troubleshooting (substitution is the quickest way to isolate a 
problem).  If you use a non-standard connector, that cannot be done.

That 2mm will not cause a problem at all.  L20 will likely move toward 
the rear a bit if you bend over C202 and give it a slight push.
