Re: (re)Installing 80's Pro Rock'r tremolo
The studs look wrong. the studs for that era ibanez trem in that style were usually hex topped, even then, and on my hardrocker they're concave and fit up to a rounded bit on the bridge so that it rotates when you use the trem.
They came up with the knife edge later. Also the top of the studs fit through the holes on those bridges IIRC. Did you receive it with the studs like that?
as far as missing the saddle and the block, pray you find it those things are hen's teeth.
