Hey Finn,L.D. is right.I've heard the mustangII works good.I had thought about it for my 37 and running the neck up through one of the bed boards or rather make a little trap door to raise and refill. I've seen some that used a recessed stainless still piece with a little "lid" on it. Sort of like the kitchen sink dish drain with a lid on it...understand???? Catch you later Finn, check your email.
