Wishbone differences
 

Will classic alloy wishbones fit a newage

The will physically bolt up but you'll need to fit a spacer on the front bushing mount. IIRC, the front bushing is narrower on the classic and will be loose when fitted to a GD/GG.

With that said, there is no reason you'd want to do that, to be honest. Just source GD STi alu wishbones. Ideally use the high caster Spec C wishbones. Actually one better, look into the new SuperPro Supalloy wishbones. They have caster and rollcenter correction built in. Its truly the superior way to go. I'm mounting a set as soon as they are out.

Do you have a GD or GG?
