I'm the owner of the deluxe wheel in the 2nd picture with the smaller plate. This steering wheel was re-casted and maybe the new black epoxy is covering some of it. Not sure but maybe that is why it looks smaller. However the metal plate does look slightly different.
I clicked on your links. you have a beautiful car Harold. I have seen a lot of nice cars on here and hope to get there some day. I will probably just enjoy the one I have and work on getting a 400 in the future.
