Hey guys, I bought an excellent condition 1973 Datsun 240Z back in October that came with a ton of extra parts, memorabilia, and documentation of nearly everything. The person who I purchased the car from is a good friend who's currently moving out of state and found this manifold during the moving process. Can you help me identify the model? Thanks! PS: my car currently has an L28

Looks like it is for the emissions equipped L series 6 cylinder engines. The threaded holes are for the AIR system.

Any pictures if the ports, and then flange thickness?
