The TPI between a barrel with square threads and one with "V" threads is different. The others are right. You could mill the locator notch in the threaded area, put a latch hook on the barrel, and find all the hardware (Not cheap if you are buying) for the forearm.
I was checking out a 99 on Gunbroker that someone was halfway through converting to .358 WIN. Macmillan barrel, fiberglass stock and forearm. I was checking into it as a parts gun, but it sold outright in a day. Fireball, was that you that bought it?
I don't know when they dropped square threads, but the solid frame models were "V" threads way before 1 million.
