I have a Penn Squall 50 two-speed. The speed change button must have rattled loose on a trip, and I lost the button cap, the springs, and all the parts under the button. I've ordered the replacement parts, but I can't figure out how they all go together just by looking at the schematic. Every tutorial photo I see has the "Shifter Catch Holder" with the pins and springs still in it. Any help would be greatly appreciated. I hadn't even used this reel before I lost the button!
