69 chin spoiler brackets

[69rs]

I am replacing my front spoiler. The old one
had no brackets, so it was flimsy. I got the brackets with the new one and I
understand how it all works except for the middle bracket. It's 15
or so inches long round bar with flattened ends with holes for the bolts. Here's the delema, One end is bent at an (45degree?) angle and the other end is straight. Which end attaches to the spoiler and what does the other end attach to? The only thing above it appears to be the fan shroud.
