Sorry I don�t have pictures, but here are some tips. The two mounts I am familiar with are the small block and big block mounts. The tall ones are for the small block and the short ones are for the big blocks. The short ones help the engine clear the hood. I had a small block installed with big block mounts, but could not install headers without swapping to the taller small block mounts.
I don�t know a thing about 307 engines, so I can only guess. Are there other sets of holes to mount the brackets to? Do you have an assembly manual? It might show which holes to use. My best guess is that there is more than one way to mount the brackets, and you need to mount them the other way...
