I'm not trying to tell you what to do, but if it was my family heirloom I would not put a conversion cylinder in it. I don't see the point in the whole conversion cylinder thing myself, The things cost more than the gun. If I'm gonna shoot 45LC I will buy a SAA. Track of the wolf can hook you up with nipples, and Dixie gun works may have the parts needed to get her going again. Just my .02
