73 dart v8 removing heater and a/c

Down load this. I know it's for a 72 it can't be much different.
72 service manual: [ame="http://www.abodyjoe.com/pictures/Misc.%20car%20info/1972%20Plymouth%20Chassis%20Serv%20Man.pdf"]http://www.abodyjoe.com/pictures/Mis...Serv%20Man.pdf[/ame]
It might down load slow.

Thank abodyjoe for the link.

The thing in the circle to the left maybe for a vacuum reservoir. But not sure.

Hope this helps.
