I'm in the process of rebuilding my 33 Plymouth door regulators. I bought rebuild kits on Ebay (Champ #985 5-Tooth) But when I finally got to removing the rivets to install the new pinion gear I noticed that my regulator pinion assembly was a different design than the Champ kits. The regulator I have is stamped FERRO 16320. This is the drivers side. I don't have the passenger door regulator removed yet, so I don't know if it is a FERRO regulator or not. Has anyone else run into this problem? Is there a kit available for the FERRO regulator? Here's pictures. thx. Paul
