I Installed the Classic Auto Air Conditioning System, Did a few Mods to it for my Liking.
I put the Sound Deadener/ Foil and a New Jute Pad, with the Big Block and Headers, you can still feel the Heat coming thru and I am a Big Guy - I sweat
, Nothing is better than driving to or from a Cruise and Having the A/C turned on, Driving in Comfort. I drive it Spring and Fall, when the Windows Fog up, I turn on the "Defroster".
I feel sorry for the Stocker Z-28 and BB 375'ers who want the Factory OEM when its Hot.
X2 to Buying the OER Center Outlet and a New Dash Pad, I liked the Classic Headquarters Dash Pad - It's worth the $$
See Post # 11 and # 14.
and My Post from my Install, just has some Good Info and Pic's.
I would say the One Thing I wished I knew while Installing my Evap/ Heater Core Box is the Classic Auto Air had the Drain Tube Fitting come out the Front thru the Firewall.
I laid out that Hole Placement per the Instructions, it Needed to be a little bit more Towards the Center of the Car I believe, You want the Drain to be at it's lowest point so all The Water Drains out.
Just pay a little more attention as to where the Drain goes, Maybe the Vintage Air goes straight down ?
Good luck, and Enjoy the "Cool Cruising"
