Someone I know wants to buy a hardtail MIM Strat,however,he wishes it to have a hardtail bridge;as far as I can tell they don't make one.

He doesn't want to block the trem with wood,I don't know why and I won't argue.

Is it possible to just swap the bridge to THIS,for example?

any help is appreciated

That particular bridge wouldnt work so well as its for string thru. If you get a top load fixed bridge it might drop in without to much trouble. Or the screws for mounting it might need to go exactly where the big hole for the wammy is. He may have to change his plan of what guitar to buy.
