Waited a long time and finally got my VTDA, complete install here. You'll need a phillips head screwdriver, 10mm socket with a long extension, two # 10 screws 3/4 inch long and a #4 allen for the VTDA mounting Bracket.
Remove the screens with a soda/beer can or punch them out with a flat piece of metal, I wasn't saving mine so I just cut them out with a dremel tool. This is a reman extra I had and it had screens at one end only. None on the outlet side.
