I finally got around to hooking up my oil pressure gauge. I used the factory oil pressure sending unit hole, directlly under the oil filter. I really wanted to keep the oil dummy light on my dash functional so I ended buying a few fittings & running a T so that I could have both. Also important to note that the threads for the factory oil sending unit are 1/8" BSPT (britsh standard pipe thread) not the standard NPT that we are used to. Since the hardware that came with the gauge was NPT, adapters had to be used. running it into the T required quite a few fittings, I ordered all of them from McMaster Karr.
Here are the McMaster Karr part numbers for everything I used.

The nipple screws into the the block where the factory sending unit was, T scres into the nipple, factory sending unit into the the T. The the 1/8" BSPT to 1/8" NPT adapter into the final leg of the T & the fitting supplied with the gauge into the NPT adapter.
I do NOT recomend using the plastic line like what came with my gauge. I fully intyend on replacing this line with copper. I am worried that the plastic line will get brittle & break, but I went ahead & used it anyways for now, will go back & replace it soon.
Remember how nice & clean my block was before? Now it is coverd in mud stains, I guess that is what wheeling will do for you.
