I have both. From what I gathered, the CJ embossed seats were the base or basic seat. I have a set that has a fold 'n tumble rear, so it at least went through 1985. The Laredo seat were the same frame, but a much nicer two tone pattern with two vertical stripes and carpet on the back and outer side. The frames are tubular and flat metal peices that have the foam poured around it when made....meaning I don't know if welding a broken one back would be an easy task.
