Big block exhaust manifolds

The casting numbers are 2946729 drivers side which decodes to 68-69 A body 383hp and 2806900 passenger side which decodes to 67-69 B/C body 383/440 hp. Both are in unrestored condition with no visible cracking or damage but both need some media blasting to 100% confirm, there will probably be some pitting. The heat riser on the passenger manifold is immobilized and the flapper/weight/spring are gone. Looking for offers around $1k, will ship (you pay for desired service provider/level/insurance) and I'll take PayPal if you cover the fees and have a confirmed PayPal address. Thanks
