72bowtie & GR8-68, thanks for the quick responses!

Oil pressure sender- now that's slightly important, but I never thought about it, or saw it mentioned anywhere in the rebuild manuals I've got. Looking that up, I see that I've got yet another hole to fill: the alternate mounting above the oil filter.
GR8-68, is that a tube coming from yours? Where is the actual sender mounted? The photos I'm seeing show it right on the engine block, often with an angled fitting.
Yes, those are the 2 bellhousing holes I meant. What are they for?
