Do I have the wrong lower control arm

Crap, I just realized that I might be being a little too hopeful about the QA1 k-member. It says it's for the 70 a-body, but it says small block, so I wasn't really thinking it might not support the slant six. Uh oh. It's ready to be picked up tomorrow. Now I'm wondering what to do if the mounts don't fit!
