Similar deal here....back seat back for my '67 Dart 'vert had to be completely disassembled and resewn so the upholstery would take on the concave shape of the seat. called Legendary on it...they said send the whole seat to them to install (said my shop doesn't know what its doing....HA!)...can you imagine what shipping a seat back from Canada to them ( and, most likely back) would cost? Cost me $1200 to have it installed up here....not impressed.
