Need advise bolting a np445 to a 325 poly

He'll have just as much money wrapped up in finding all the old stuff to work, plus the aggravation of finding all of it and now he has a bunch of weird stuff that's hard to find replacement parts for. Or he could use the Hot Heads adapter kit. I'm not gonna lie. It was expensive. Mine was a tick over 700 dollars shipped, but it's nice. It's worth every penny.
