Rear Bumper Arm Assembly differences...
 

I know that several years ago, I believe it was Marco that posted some info regarding the differences between the Rear Bumper Bracket Arm assemblies. I think the info was more geared to 1930-31 models, but I am trying to determine differences for the 1928/29 models also. More specifically the 55A Tudor Sedan vs. the Fordors and Phaetons. Has anyone made a comparison chart that they can share?
