I have been offered a set of (I'm told) original long branch cast exhaust manifolds for first gen. birds. Cast numbers are - L/H 9779495 R/H 9779494 Does anyone know if these will fit for sure, are they rare and what would you expect to pay. I don't want to buy on a gamble, but if they are something special and I can get them at the right price I could always sell them on if they don't fit my '69. Jerry..
