I have the steel oil pan with the 'U' like engine bracket... Which bracket do I have to use other than #2?... Also looking to upgrade #4 to Poly Motor Mounts.

Do I absolutely have to use the bracket that goes in between differential cover/oil pan (#1)?

And do I have to use the bracket that goes in front (#3)?

Just need to know because I know 04 GTP's is a weird yr.
