I sent off my 65 3" years ago. I sent it to a Smith to put a different cylinder. I wanted to switch it back to stock. I discovered that the Smith had cut the yoke to accommodate his work. I would like to find another yoke. I checked Numrich gun parts, Brownell's and E-bay. I found a yoke on E-bay. However it was the old style.
Amy suggestions on where I might find a spare yoke for 65-5?
