1968 dart GTS black bucket seats for sale
I shipped a pair of 68 Charger buckets in 2 boxes through USPS, shipping was actually cheap, can't exactly remember but want to say around $50-$75. I took the seats apart so the fit in a flat box, I didn't ship the seat tracks.
Good luck with the sale, that is a great deal! I sold mine on eBay for almost $400 and they needed new foam and covers, no seat tracks or plastic hinge covers!
