Chris,
If you're referring to the OHC L6, The factory bracket needed is unique and somewhat hard to come by.
This was used from 1966-1968 on any/all OHCs with AC both A-Body & F-Body.
If you aren't aware, we have a Facebook Forum Page dedicated to the OHC 6 engine.
You might want to check it out. You can join in and add a wanted post.
May get a response from one of our many members.
Cheers.
