I have a 60/40 blk/gray set from an 03 EDGE with <40K miles on them.
there is not bracket but I believe you can take the slider tracks from your and bolt to these.
I took my slider tracks and bolted them to a set of Fx4 Buckets from an Ext Cab so it has to go the other way.

$150 + shipping from MA, zipper 01930

Shipping will be the killer, because they will need a big box and I do not have one so the packaging guy will have to supply; plan on $150 or so maybe more. Sorry...
