Big Block Truck Headers/Exhaust manifolds wanted

Stock manifolds on my 78 were both center dumps, same manifold left and right ... Some class A motor homes have the same manifolds... I do have a pair of truck, center dump manifolds left if ya need em... Tweekin the frame rail was no big deal... ya could always bend it back...My truck was rare 1 of 74 built in 78... I traded it for a 67 Barracuda...
