I've got that same drift punch assortment. kingpins from F150s up to KWs. and a big hammer. I've got an 8lb sledge with a 10in handle. really handy when you dont have much room but need to smack the heck out of it.
My 4 lb metal handled Estwig usually does the trick. If that doesn't work it usually takes two of us with a sledgehammer. One to hold the drift one to swing
