I know it doesn't help with your current lever, but I have replaced levers on many Marlins now. I used to order Wild West big loops, but I always ended up wrapping them to close them up a bit and not be too large. Then I tried the Ranger Point medium loop lever, and that is what goes on all of my Marlins now. I have never had a fit issue with either of them. The shipping from Wild West usually takes 2 weeks or so, but Ranger Point is super speedy. I have had great luck with both of their customer service departments. If you email Ranger Point, you usually have a response inside of 10 or 20 minutes. Again, I know it doesn't help with JARD, but if you decide to go a different route, these are great options.
