I had to buy a top block with flash and mode/control dial assemblies intact. I also found the service manual which wasn’t as helpful as I hoped.

I took the top block off and served one of the assemblies because it was under another assemblies and the camera was stuck in manual setting until I fixed it last night. Interesting part is when it was stuck in manual it couldn’t tell if the flash was up because of micro switches that are part of the assemblies of the mode/control dial.
