Emissions?

I have an 86' CJ-7 w/ 258. I just installed a Borla system ( header, muffler,tail pipe, Random highflow CAT) My question is, I have run into a problem with the "air tube" running to the CAT. It's too short, about 6-8" too short. Can I plug the air port and still be operating properly, or were can i get the tube to replace the one that looks like it was cut to far back. Also, were can I get the smaller EGR tube that goes from the exhaust man. to the intake. The one I have is heat welded to the nut.
