I cannot believe I finished putting in my new "Perfect fit" A/C system. I had to wait over 2 weeks to get the system once I ordered it. Then when you received the system for a 71-73 mustang be ready to make lots of calls to the company. All the instructions I received were in black and white photocopies and were for a 1970 mustang. They lined out the parts for the 70. It had arrows pointing to places in the pictures but since the pictures were black, all I saw was the arrow. I had to modify the A/C bracket and I think they had my 2 year old nephew write the instructions it had some "NOT ALL" the pictures. I guess they ran out of film and had to make do. However, the Tech line was great. I order new instructions 2 weeks ago still have not received them but finished it anyway.
