Found them in the open area on the front side under the intake manifold. Probably a dumb question but I wanted to consult y'all and see if I should just go ahead and buy metal vacuum lines? Also is it a difficult thing to install because I'm leaving for a trip soon with the car back to school. Also any other concerns I should have?
They could be a source of your idle problems. I've used Rodney Dickman's stainless lines and they were a perfect fit for the 86 I installed them on. He now offers an EGR valve extension for the 88, due to the relocation of the valve, a little more to the left of the engine bay. So, if you have an 88, let him know, else the EGR line won't reach the valve.
