Gen3 Swap mounts for Spool type Big Block to Gen3 Hemi

[m79ded]

I am looking for who makes conversion mounts to go from a 73 and up Spool type that's originally a Big Block car, I have found from Small block to gen 3 but not from Big Block to Gen 3, Does such a thing exist or do I need to fabricate them or change to a Small block K-Member, ? Any info would be appreciated
