S&W 745 safety drop in replacement in 4566?

[Tom Fury]

I have acquired an ED Brown speed safety for the 745 and am wondering if the 745 safety will drop in to replace the stock ambi safety in my 4566/CQB.
Anybody know? Have replaced stock 4506/66 3 gen safeties before, but don't know about 745 safety.

Thanks, TF
