Not really but it was fairly easy to make it work. I couldn't find a all thread that was the size/pitch i needed to make a hold down stud so i cut the heads and welded 2 machine screws together. For a base, i took the most beat up louvered cover i had in my collection and cut the sides off. This left the top trimmed to the od of the filter for a base. I enlarged the "base's" bolt hole to match the mouth of the carb. The mouth of my carb is stepped so everything centers up nicely when its bolted down. I picked up 4 of these with assorted bases and used filters for under $10 either on ebay or a swap meet. Now i need to find new ones for my holly 94's for my flatty, haha.
