2gc carburetor 4 barrel filter adapter spacer (2 barrel to 4 Barrel)

This an adapter for a 2 barrel Rochester 2gc carb to a 4 barrel air cleaner. The air cleaner I am using was picked up at orielys and is a standard cheap Edelbrock 4 barrel carb air cleaner. In the pictures I am using the first version that I had to print an extra spacer on it as it was a bit too narrow. This version has been updated and should fit great. The diameter of the hole in the air cleaner needs to be at least 128mm and there is a 5mm shoulder for the air cleaner to sit on on the adapter
