Oil temp and pressure sending unit mounting

I obtained a Cessna instrument panel(has cyl head temp, oil temp, pressure, etc) and I need to know where to mount the sending units. The oil pressure gage is electric, 12 volts(opposed to 24, like some aviation parts are), and I need to know where to mount a pressure sending unit for this instrument. Now the oil TEMP on the other hand is MECHANICAL. Which means it has this 6 or 8 foot long metal tube with a bulb on the end of it, with a heat sensitive expanding fluid in it, probly mercury. I also need to know where I can mount this sending unit(bulb thingy). Theres a slight problem- its nut is loosely fitted, so it rotates without twisting the metal tube. The bulb has a copper squish washer on it, and a flange that the nut cinches up against. So whether i have to tap a specific hole in the oil pan for it, id have to make a flange for the squish washer so it dont leak oil. Id just like some input so I can figure out how to mount this nightmare of a panel, because 1, Id like to have oil pres and temp, and 2, it looks real cool in the bare spot on the centre console underneath the stereo rack. Im not too worried about that metal tube for the temp instrument, as it is very long. I just need to be careful with it so I dont break it, and have the fluid inside leak, ESPECIALLY if it does happen to be mercury. Any input would be much appreciated, thanks! I wanna do work on my E30, seeing as it is warming up here, it was very nice today, so i started removing some of the AC system, because im doing an AC deleat on it for weight reduction-the compressor was HEAVY, had to have weighed at least 13 lbs.
