I’ve repaired a couple of 6” rapala floaters lately with missing lips.
I don’t like how the company installs the lips. They are not much holding them in. The first couple of pictures is how they are originally notched very shallow. The wood is balsa and the strength is in the wire so i notched it out deep to the wire and made the new lip just to fit over the wire. This will hold up. I use a two part epoxy to glue it together and seal it up from the water. And I made the lips from lexan
These are the musky size rapala and they are kinda expensive

It sure looks like a Brown to me. I do not believe there are any Lake trout in Calif except in Tahoe and Donner lake. Did you catch it on light tackle? I caught one that size out of the Truckee River on 4 lb test using a Panther Martin against the current! We could not fit that monster in our cooler, a neighbor at our campsite came by to ask us how we did, I told him about my Brown and how big it was and he kind thought I was exaggerating.....until I showed him the fish and then he could not believe that I caught that fish in this small river! I was able to get some pictures on our instamatic camera and ate it that night. We drove into town the next morning my family and I in my Camaro and my parents in my dad’s F150. As we were driving into town, I was in front and my parents behind me, I could see in my rear view camera, that someone had left the camera on my dad’s step side! So I signaled my dad to pull over and as we were I saw the camera fall off the step side and my Father ran over it! That was the only proof of the biggest trout that I ever caught in my life, and its just a fisherman's story now!
