H & H Classic Chvey Parts in Bentonville has a very nice illustrated catalog they will send you. Or see them at swap meets in TX and OK during the season. I've bought virtually every for my son'd 57 BelAir 2dr from them, quality people, quality parts, quality service. They sell the complete upsholstery kits which are the way to go if you want the factory-right interior for your car!
H & H is in Bentonville AR. They attend the Petit Jean Swap Meet in northern Ar, the Decatur TX Swap Meet at the end of this month, several meets in Arlington TX at the Ballpark, The Chickasha OK meet in Oct, and many others.
