You are correct about Sta 740 Bulkhead in the aft area of the Fwd Cargo compartment. We would actually cut a 14" x 18" access opening in the bulkhead web to gain access to the FWD Bottle Bolt Casting when they required replacement. Most of ours were being replaced due to Corrosion. Once the Job was finished we would install a doubler over the cutout with Hi-Loks. STA 950 was also the FWD Bulkhead in the Aft Cargo compartment.
