I didn't realise you were having problems lining up the holes on the frame. In the pictures in your first post the mount looks like it is bolted to the frame.
Supercars has part thru 70's only no 80's and checked mounts none for 307's.......appreciate your helpI heard these issues with cheap Olds mounts. Supercars Unlimited is the only place that sells different rubber mounts than the Chinese Anchor mounts everyone else sells. Either return and try another set or grind to fit. Thankfully I have enough extra factory mounts to not need the aftermarket replacements, I will get the Supercars Unlimited mounts when I do.
