Looking good man. I did the same thing on the transom, used screws and fender washers to suck the new pieces tight to the back. Are you going to use the OEM speedometers? I decided to not use mine since they require drilling so many holes in the transom for mounting the pickups and pass-thru fittings for the tube. I am trying to drill as few holes as possible in the boat to prevent rot. I'll probably pick up some GPS speedometers (probably just one) this summer or in the fall after I use the boat and see what I like.
