Re: !977 AC Question
 

Have the AC in my 1977 working great at blowing out 35 degree F air through those tiny ducts.

Years ago before I got my 911 I seem to remember an aftermarket duct kit to install additional ducts along the dash knee pad.

Am I remembering correct. If so does anyone have a source.

Would like to get more air volume to cool the interior.

I don't know the source and cannot answer your question - sorry.

However I do have a few questions if you don't mind.

1. How did you get your A/C to work great?

2. Are you using the original hoses?

Try Griffiths for the underdash vents, i heard you can get them for cheaper elsewhere

Try Rennaire...they are having a sale ...i may just buy these items

1977 AC
 

Still using R12. Pumped down the system for over an hour before
putting in freon.

Do have an updated more efficient condenser.

Hoses are original as far as I know. There are in great shape.

Where in Michigan are you located??
