Here are a couple photos of what my Son in Law and i did.
Forgive the quality, I didn't have my camera so used a Blackberry phone camera.
Here is the bottom of the RZR seat, note the silver colored pressed in nuts about 9" apart. I cut two pieces of 2" steel strap 16" long then drilled anc countersunk the 2 holes in each to fit the seat and used flat head allen screws.
Here are both pieces fastened on.
Next I laid out the spacing for the slotted holes in the stock seat pan which were about 13" apart then drilled and tapped 3/8" holes and added bolts from the back side so they act as studs.
And here is the seat pan fastened in place. Note I placed the studs approx center of the slots so I still have some for and aft adjustment for different sized drivers.
Many thanks to Tom Tanner and Stuart at Best Manufacturing Metal Fabrication in Glendale AZ!
