Thanks! I’ve been blowing out the frame with air as I go, and it’s been pretty clean so far. The front had quite a bit of grease from an apparent oil leak, but I’ll hit it again with a pressure washer once the cab is off.
For the oil pan, it’s FPG CS8510 at Napa. The reason it’s difficult to find is that they list it as a ‘conversion set’ instead of an oil pan gasket.

You can also buy just the pan gasket itself, FPG OS34500R.
