Hey rustywrangler, this is a great write up! I have tried two sets of seats that I have lying around, and they seem to sit too high on the front.
I clicked on the link that you have, and my only question is this;
With all these direct bolt-in seats, did they require the use of the YJ sliders?
"...either directly bolt into the stock sliders/risers or, with minor modification..."
I do not have anything from a YJ as far as seats go except for the risers.
