Blazer or Suburban hatch arms

[jlmerie]

I was digging through some stuff in the barn and ran across these hatch arms. The only problem is I can't remember if I took them off a suburban or blazer. Is there an easy way to tell which they fit? I assume they are not the same. The first 2 pictures are of the arms in the down position. The second 2 pictures are of the arms as they have "locked" into place while the hatch is open. Any help would be appreciated.
