Thank you for all the effort you are putting into this! I just bought a JL a few weeks ago and installed the Misch 4x4 brackets. My knees are no longer mashed into the dash but I sit up too high and my head rubs on the freedom panel. I inquired at a local shop to modify the Misch bracket and chop/weld the seat base but they won't touch it for liability reasons. I'll be very interested in your new brackets, It will be nice to see some of the sky and traffic lights again!
