I have seen the prices for these anywhere from $1200.00 to $1900.00 on the buy it now prices on Ebay.
Of course sometimes someone asks way too much and they go unsold and I have seen a set of brand new Laramie take offs go on the auction format for just $760.00, that was a deal to whoever picked those up.
Bottom line is how quick do you want to move them and are you willing to ship. If you go the extra mile and offer shipping you will get more offers. You will need to find out what truck terminals are close to your area and be able to drop them off when the deal is done and you have the money in hand.
Good luck with the sale.
