Greg,
I didn't go with anything fancy. I just used a single screw loop type restrainer. You really can't see it in my picture as it is just barely visible. I tried to find you the air tube hose but could only find one for 77 and up. However I am sure you will find one. The blower motor (originals) are different then a non ac car and it could overheat without it. Looking at the 1977 hose it probably could be modified because the ac box connection is the same.
