Worked!
I was upset at first because I thought they sent the wrong part, then I put it together and the spring didn't work....then I realized I just had to spin the screw to turn it the proper direction for my stovetop.  After my 3rd attempt at this DIY project I got it to work.  Its my fault for rushing so make sure you look at what option and direction you need it in before starting.
