OK. Since Kamikaze isn't close enough to consider checking with on scraps.
Checking with cousing for scrap aluminum if not I may take my wood template with all the holes on it to Stainless Marine to see if they can provide the smaller plates or even make a square piece of aluminum that would slide over all of the screws!
Hoping to get this ready before I head out Friday on vacation so that when I get back it's motor time!
