I tried to search but I couldn't find exactly what I was looking for. I am curious as to if the gen parts fit the 45.5 chrono PO. I haven't seen any franken chronos so I figured I'd ask. I'm considering gen tube, crown, bezel, and a relume. I was considering the bezel insert off of ebay but I have heard they are luck of the draw as with the rep bezel insert. To my knowledge they don't sell just the GEN insert, only the bezel. Any help would be appreciated!
