Fuel filler lid locks

So I took my 98 through a car wash and it froze the lock on my fuel door, I de iced it and what not and when I unlocked it the spring inside cracked (it was old rusty and cold) any alternatives to buying the new $75 lock from Toyota? I tried some magnets but they were too weak to keep it shut

 

There is this... https://www.tacomaworld.com/threads/1st-gen-fuel-door-lock-fix-how-to.330322/ not sure this is what broke on yours though? And it's a pretty extensive "fix" for the lock. I have heard of people using magnets as well. Maybe you just need to find some stronger magnets. I was surprised too how much a replacement lock is for our trucks.
