Here is an original carburetor and manifold adapters/extensions to be used with accessory carburetors and manifolds:
This straight, aluminum adapter measures about 3 1/2" long. Both ends have mounting holes that are about 2 7/8" center to center and the bore is about 1 5/8". The mounting holes on one end have been enlarged, but it is still usable and in nice condition.
Take a look at the photos, what you see is what you get.
