Here is an original carburetor and manifold adapter/extension 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. The price is 30.00 including shipping in the USA. I will ship outside the USA for extra. I accept PayPal for payment. Please email directly at: [email protected] or call 734-730-4274. I DO NOT CHECK PMs. Thanks.
