Bruce, very nice job, I'm glad it worked out for you. I have since went and bought and/or sorted through extra tools I have and feel I have most tools needed to make a repair or help others stranded.

My first design was nearly exactly like yours but found out I had to space the frame away from the edges. I realized the factory floor cover did not have the hard board backing all the way to the edges so I had to compensate.

Nice job, James
