I hope this is the right place to post this: I'm looking for a new or lightly used A/T 756400C (case only). Putting together my L3 application and design documentation, that'll include a 75 mm M1315W A/T motor. I have the fore and aft closures but am missing the case and 75FSDSS (sealing disk). Let me know if this should be posted elsewhere. Thanks. Gary
