3.1 broken crank sensor

I have already broke crankshaft sensor on 1992 Culass 3.1. I could use some help on procedure to get the oil pan off, looks like that's the next step. Thanks for any HELP.

The crank sensor on these engines goes through the engine block. The only thing inside is a reluctor wheel that's cast a part of the crankshaft. Sounds like you could really use a service manual.
