I'm New Here
I purchased RV8 Flymore Seats (Jon Johanson) and would like some tips on mounting these in the RV8. I looked at the photos on their webpage and would like input on making the brackets:

What material and thickness to use, what bolts work with the seat, and how to mount the brackets to the floor?
