I say give it hell. If it works cool, we all learned something. If it fails, big deal. I am sure that $250-400 you spent on it isnt keeping your food off the table at home, so the “savings” is really irrelevant when it comes to gaining experience from trying something.
Plenty of people, some that chimed in with dumbass replies have made far more DUMB decisions retailed to cars than trying to fix something like this.
