Tom , sorry for the delay ; DW had packed my camera , for our trip south and it took me a while to find it.
#1 Drivers side above floor.
#2 Passenger side above floor
#3 Drivers mount bolt below floor
#4 Passengers mount below floor , taken from wheel well.
Because the pass. side is mounted further back and in from the wall than the drivers side , they had to weld the extension on the tube frame to anchor the bolt.
If these aren't all you need , let me know , I might not have internet tomorrow, but should have when I hit Vegas on Wed. night.
