oil pressure gauge issue

[SS Shaun]

ok so i am trying to clean up my garage and while i am doing that i am putting some parts on the chevelle that i have laying around. So i am trying to install my oil pressure gauge. I put that elbow in and its hitting my z bar. I wasted my money by buying an auto meter kit and same thing it hits the z bar. i am lost and dont know what to do. I am to the point where i am going to plug it back up the way it was and just roll with no oil pressure gauge, Its NEVER going to see the strip and if my oil pressure goes the motor is toast already right? what should i do? thoughts/help please!!
