1) You really do not need the pressure switch, just check your oil regularly, if you ever see that light go off that means you already have some major damage to the car. (so plug it up and be don with it)
2) As said, you can get an elbow fitting instead of that 3 way fitting you have the sensor connected to, and then connect the 3 way to that OR an elbow fitting instead of the fitting that comes out of the 3-way and obstructs the alt. bracket.
3) If you are worried about the pressure switch light, get a pressure sender that has both an oil pressure terminal and a warning terminal, same cost as a regular autometer oil pressure sender but with the additional warning terminal that goes off if the pressure drops below 11psi; very useful because it's never supposed to go under 11-13psi even when the car idles. You can just hook the wire from the stock pressure switch to the Autometer one and it'll work just fine.
look at the link below, last pic is what i just described.

Actually now that I look at mine and yours, I have 3 pices too, but my last elbow is shorter so it fits. So get a shorter elbow and maybe see if you can arrange it like I did.
