Yep. It's the main galley on the LH side. The engine is entirely assembled & ready to install except for this. Been checking with everyone & every source I can think of. Unfortunately, all the guys I can think of that could answer this question without doubt have been put in the ground years ago. And I don't think any of the old timers that really know this stuff ever got beyond a black & white tv or "party line" for communication let alone the internet. I would love to go back in time & learn a few more things off my old boss. He would just respond to this by saying: "you stupid kid, you think your a mechanic!!! Anyone who turns a wrench for a living would know to -----. Do I have to show you everything?"
Looking back, that mean old grump wasn't mean. He was just pushing me to learn. He would be welcome in my shop now anytime LOL!!!
