I'm just trying to gather all my stock parts (headlights, seat front bolts, stock front speakrs/tweeters, etc.) from all over my garage and put them away in several boxes so I have everything in one place.

One thing I don't remember is,

When installing the spoon x-brace, were there any stock bolts to take out that had to be replaced by the bolts supplied by spoon?

 

Yup, four 14mm bolts have to be removed. Just test fit brace up there and you'll see them.
