Transmission Mount question

[ImpSvcs@xxxxxxx]

Good Afternoon All,
       My parts manuals show a unique part number for 1959 and 1960 Convertibles, PN 1533 850.  This mount is shown as being used on 1955-6 Imperials as well.

       I have seen (and drawn) an aftermarket mount that I was told was the replacement for 1533 850, but would like to get first hand information from someone familiar with this particular piece.

       Please contact me privately (offline) if you can help me with this.
 
Thanks,
Steve Charette
