Quoted from KING-HENRY:any real thread with pictures and guide on doing this? I hate the thought of dicing things up on a nice machine..what I mean is that I do not want to devalue my new pin. Other mods don't affect this. So how do we mod this to emulate a premium/LE??? many thanks in advance.
You can't emulate the PREM/LE experience exactly. The biggest issue is the PRO software doesn't support the spinner in the matrix, so you need to piggy-bank on one of the rollover switches. The plastic grinding is a bit sensitive to the purest, as is the new concealed hole you need to drill on the TOP of the playfield behind the ball guide to attached the spinner bracket. (ouch).
That said, a number of other folks have done the same operation many times without issues.
