Did you talk to Larry at the upholstery division in Tempe, Az? He makes all their kits and if he has the right materials, I'm pretty sure he can make them. Probably not that much market for them or they may not have a good original for patterns.Nope, they don't. Only Impala stuff for 1959. But they do have anything and everything for any other year.
Classic Industries (in California) should have it.
