Boost/vacuum gauge......I would just tap into one of the small lines that comes off the block on top of the plenum. Another good one is coming off the line going to the fuel pressure regulator. I ditched the plastic line and went to reg rubber vac line, then T'd off of it for my boost/vac line. Just use a small piece of rubber line to connect the hard plastic vac/boost gauge line to the T, and use 2 small zip ties to keep it from blowing the plastic line out.
Oil pressure gauge.......as was suggested, just find a brass T fitting and a short piece of straight pipe/line that will screw into the place where the oil press sending unit is at. The pipe nipple is to simply connect/extend the T out far enough for a little more clearance/room to work. Make sure it's a female fitting T block though.....then screw the sending unit into one side, and the gauge line into the other. It's been a while since I did that one, so part sizes and what's exactly needed are a little fuzzy...lol. The factory sending unit is on the driver's side, lower front of the motor....it will have one wire coming off the end of it. If you use an electric press gauge, just run the signal p/u wire off the same sending unit. Stock setup only turns on an idiot light, but it's still a pressure transducer, so you can use it's signal to run a gauge as well.
