getting rid of a/c

[hbomb]

I have a 88' gt and am in the process of cleaning up the engine bay and replacing alot of parts with show quality parts. I got a alternator, idler, power steerig bracket kit and I am also getting rid of the air conditioning. I noticed that there is a black metal tube that goes over the lower manifold which branches off into the manifold. The rest goes into the firewall. Has anyone removed there a/c system completely? How do I go about removing the uneccessary hoses? I'm removing the heat exchanger too. What do I need to remove with this?
