Harper - 2 questions if you get a chance.
Have you considered relocating the transfercase switch - replacing with the dual cupholder? I haven't actually seen a 4R with the dual cupholder, but the part is available in the catalog and the owners manual shows it. I would replace the switch with a rocker type switch - as there's really on 3 modes, 4x4h, locked 4x4h and locked 4x4l. I would retro the center diff to an OE switch in one of the blanks, that would only require a rocker switch between low and high.
Also, since you've completely removed the 2nd row before - have you been able to compare the flip up seats to a 4R with the 3rd row? I have been wanting to convert my 4R seats to flipup - but would like to compare. Only people with 5G's around here have 3rd row
Thanks!
