Side plate
I just made a template out of cardboard and then transferred it to a .032 sheet. Used cleco clamps to hold it and did the final trim to get it to fit correctly. Make sure you account for the thickness of the floor while fitting and before you drill your mounting holes. You'll also have to decide how high you want it. I chose 4", but may trim it down to 3" or 3-1/2".....not completely sure yet. I did the same thing for the front arm rests.
