I don't know if the Model A suspension travel is enough to make a difference either.

Looks like something for your next project...

Yeh, I was concerned about going behind the diff. Other responses suggest that the result would not be worth the effort.
For my next project, I think I'll make one that attaches to the diff as shown above. Thanks, all.
