How do you put a new bail spring in a mitchell 300a reel?

To replace the bail spring in a Mitchell 300A reel, first disassemble the reel by removing the spool and side plate. Locate the old bail spring and carefully detach it from its mounting points. Insert the new bail spring, ensuring it's properly seated in place, then reassemble the reel by reversing the disassembly steps. Finally, test the bail to ensure it operates smoothly.
