I got carried away collecting Webers and parts. I'd need to count how intakes I have. One is a Speedwell, some have names others don't. Some have provisions for linkage and vacuum take off. Some will work without bulkhead mods others require Weber box. I can offer 45 DCOEs to match, linkage and air cleaners no longer have 40s. Steve (CTR)
