After many a year of infrequent use I picked up my S470 ibanez and after a while I noticed the tremolo was wobbling in its slot. Eventually I unscrewed the bar entirely and took it out only to find the cracked screw in slot.

So it's about damn time I get it replaced, but I would like some advice. I never really warmed up to the screw in nature and always liked the way the edge tremolos functioned. Ideally I wish to know if anybody here could tell me if it's possible to replace the arm holder and arm with a Edge Pro variant?
