Dropped the steering rack and lifted the engine for clearance, and then dropped the pan. No serious surprises. Found one of the water outlets was massively corroded, amazed that it wasn't already leaking. A replacement and a few additional gaskets are all on their way now, as well as new rack mount bushings and a new steering coupler. While I wait for parts, I've been reviewing what I'm going to need to make the A/C work.

I've included a new pic from the day before I started tearing it all apart. Looks pretty good with the exterior and now interior largely complete.
