Runway Arresting Barriers

Greetings,
New member seeking drawings or photos of USAF runway arresting gear from the 1960’s and 70’s. The particular type of [8D] equipment had the DOD designation of “BAK-9” and “MA-1A.” I hope to build an runway diorama incorporating the arresting & barrier equipment. Any former USAF civil engineering crews out there? Thanks for any assistance.
