i would say that is a stretch, especially for the condition they are in. as they are now, the protection plates are bent to crap, will have to be straightened and refinished (NLA), the swingarms will have to be disassembled, blasted + powder coated. used swing arms have typically been valued at 500 to 750 bucks for the pair.
IF, they were stripped, cleaned and powder coated ... with reconditioned stub axles, new bearings, rebuilt brake calipers, then, even with used disks and reconditioned protection plates ... they would be worth between 1500 bucks +/- a little.
