I have 1 unit left from the original 50 I made. All positive feedback. The first picture shows the kit I provide and the second picture shows a completed unit. It uses a Fram PH8a filter for a 460" Ford providing great filtration and oil flow. It will fit any post 81 M30 with a downwards facing canister 3.5" across. There are only 2 canister sizes, 4.5" and 3.5" I can also make them for the early 4.5" canister but need a minimum order of 3. $155 shipped in the USA
