Yep, those pans are only made for pre-86 13B's, and will not fit FC or FD 13B's with stock engine mounts.
You're going to redo your stock engine mounts just to get this thing to fit???
I doubt having a beefier oil pan flange will actually make the engine stronger...
Under 300hp 13B's should not need it.
Over 400hp 13B's should seriously look into dowelling.
Another option is to go with the Banzai oil pan engine brace?
I would never use it on my cars though...
