Here is a product that I have been looking around for many months. When I was doing my forced induction projects finding a MAD adapter was like looking for coin on the beach. Contacted many places and site and no luck.
The only one I know of is the HKS Mass Air Flow Sensor adapter, but that thing is about $50. Here is a product my neighbor introduce me with. Its black color made with high temperature hard plastic. This maf adapter also comes with a gasket. This high quality maf adapter are $15 each.
Below are casted aluminum from HKS. Structurally they are the same, but different material. They are $50.00 each. The below Buy Now Icon is for the aluminum HKS MAF Adapter:
