PS if I ever get a chance at a new style frame with this problem that the factory will not repair for price that is worth the risk. I will try to remove the new style lug and replace with an old style pin and staked type.

No, I will not try it on someone else's frame. I do not have an FFL of any type. Receiving a frame, working on it and shipping it back would be both a hassle and illegal. I can only receive a frame with the intent of keeping it.
