71 skylark diagram for ac/heater duct work.

would anyone happen to have a diagram of how the ac/heater plastic duct work connects to each other they would share with me? When I got my 71 skylark all the pieces had been taken loose by previous owner and was in the floorboard. I think I am missing a piece or two. this is the duct work from the defrost down. If I had a diagram it would tell me if there is pieces missing. I think I should invest in an assembly manual.


Thanks in advance
Michael

that picture you posted does not show defrost duct. Im so confused.

 

The defrost duct goes behind everything, attaches with tabs at the top, fits over the opening on the top of the heater core box. One screw holds it on through the metal tab that rotates on the bottom.

 

Maybe this will help?
