Agreed on the part you are removing. But in my case (1967 is an odd ball year and the 68 and up repros are not the same) I would have to remove one from a doner assy which I could do on the bench but if the tool works well why not use it.
Got an idea (Tim Taylor grunting going on in my head) cut the pin off the threaded rod. Drill the end out to accept a pin the correct size, or better yet a roll pin punch, the type with the round dimple on the end.
OOH (More Tim Taylor grunting going on in my head) and to protect the replacement handle drill a hole into a piece of oak or other strong wood the ID of the handle OD and cut it in half to form a cradle for the jaws to hold. could be used with a small c clamp to put the handle back on too!
