I have an STX-38 Black Deck. There is a large spring that holds a tension pulley and that pulley holds tension on the cutting blade belt. The spring snapped off...so I ordered a new one. The issue is now I look under the chassis and I don't see where this spring hooks in. I have the technical manual and it has nothing in it to help. Any one out there with a similar mower have an idea?

The dealer was not so helpful and told me there would be a welded on hook...I don't see the hook or the place where it came off.
