Victoria Wiper and Blade

[Colonel]

I am trying to upgrade my windshield wiper motor, arm and blade to the correct type for my Victoria. I have the correct vacuum motor and looked at the judging standards as a starting place but there are no installed pictures and I am not sure if the spring is to be exposed or if it is to have a shield over it. The 8" blade seems long as it hits the top of the windshield frame. Maybe it is supposed to.

I would appreciate any help in getting this right. If you have some pictures that would be great as well. I know there are a lot of Vicky's out there that have this correct.
