My car was non a/c but I bought an a/c dash pad. So I have a non a/c car with an a/c dash, so when I ordered from Vintage Air (they have two kits one for factory air one for non a/c) I told them what I had done. They added in two reducers, two lengths of flex hose and the center dash vent opening adapter so I could plumb that one it instead of the one that comes in their non a/c kit. The one that comes for cars without a center dash opening is a vent that installs under the dash above the end of the console, kinda looks a little cheesy. The reducers are needed cause the dusts on the evap box (under dash unit) are different sizes between the evap boxes for non a/c or factory a/c, then the hose was the right size to go from reducer up to center vent adapter. They were very helpful.
