Carbs Needed

OK I am needing a pair of matching tunnel ram carbs! Holley 450 mechanical secondaries or vacum secondaries! Anybody got a pair laying around they are not using and want to sell! I would even look at a pair of 600 or 650 maybe.Needing rebuilt is OK just want complete carbs with no parts missing.If I don't find some I will just buy new ones! Just thought someone may have a pair. Need these to complete my version of a crossram setup for my 67 Dart Gasser

Thanks

Bobby
