Those are some nifty looking seats and probably great in a Honda or Acura. If you've never sat in an XJ with seats like that, you'd quickly learn that those kind of seats with the really high bolsters on the lower half of the seat make it a real pain in the arse to get in and out of the Jeep. Especially a lifted jeep.
I bought the Steel Horse seats ($190 each) back when they were in business. I really like the way they hold you in on the trail, but they are a little on the stiff side. I know these seats are still being made, just under a different manufacturer name. Fourwheel Parts Wholesalers still sell them. The only part of the design that I don't like is the lack of a quick release to rock the seat-back forward. You have to crank the large knob on the side and if you have a 2dr like I do, that's where it's a pain.
Alot of guys have snagged the factory seats from Hondas and Acuras because they have just the right amount of bolster. They can be had for a decent price at salvage yards - or look for some "ricer" club websites and check out their for sale forums for the seats. The nice thing about the Acura and Honda seats are the fact that the bottom surface is flat which makes bracket building much easier.
If you wanna see what I did, you can check out the "Tech Write-Up" forum available to members. I did a write up about my "no-weld bracket" seat install with pics and it's posted there.
BTW, I disagree with Kejtar about those Giveaway XJ seats -- they are the most uncomfortable things I have ever had to sit in. I got to take that XJ over a few obstacles on Moab Rim and got tired of those seats in a hurry. They'd be great for a buggy, but not a rig you drive to and from the trail - or daily driver.
Good Luck!
