    I always wanted a flat firewall (near flat) and I hated the GM Heater core/AC setup. Just so big, and a waste of space.

    So I scored (another lucky day) a Vintage Air GenII compact kit. I like this kit because it is smaller then the Surefit and will give me room for my next add on a new Holly Dominator Computer (next write up).

    Quick Notes to get AC/Heater Core out:
    1) Remove Dash
    2) Remove lower black brace
    3) Remove AC Dryer
    4) Remove inner fender
    5) Remove Fan
    6) Remove inner fender support
    7) Drop starter to get two nuts behind engine
    8) Remove all screws and valve cover
    9) Remove heatercore
    10) Remove AC Box

    Follow pictures for all of the fun!

    Move the AC from the drivers side to the lower Passenger Side (did I say this is going to be easy?):

    Remove Dash:

    Here is the removed Dash, this is going to get changed up:

    All that center stuff goes away:
    [​IMG]

    This is the AC Evaporator and parts, start removing it piece by piece:

    Take the FAN out and remove the heater core from the inside of the car:

    [​IMG]

    Take all of the bolts out and the lower bracket:
    [​IMG]

    I removed the valve cover and it was able to come out from the top:

    And this is what it looks like:

    Next is to mount the blank plate and the host connections:

    You should weigh the two systems, while you are at it to see the saving in weight!! Looks like there is a lot of weight removed,

    Started the mock up of firewall, the test fit of the hose end and removal of the AC harness.

    Everything is removed:

    My first test fit each adapter was very loose. I added a foam insulator and now all pieces are tight.

    I have two holes to fill ... I am going to try to get rubber plugs but might have to use the welder:

    I ordered some ABS and now started the mock up:

    Great work! I am VERY interested in your project. Strongly considering the same for my '79. A couple of questions:

    1. do you mind telling us what that kit cost?
    2. I still have the original pulleys / accessory drives. Do they offer one with an OEM looking drive pulley?
    3. How does the compressor mounting to the engine compare with the OEM type mounting (I have the long compressor, driver side).

    I did replace the heater core and evap core in this car many years ago, so I know I can do it again. However, your reminder tips in the first post are very helpful. I've forgotten a lot in 30 years LOL

    Thanks and please keep posting. Your pics and instructions are outstanding. The internet is an amazing tool for us car hobbyists.

    This kit was a craigslist buy ... it was the Gent II Compact unit, condenser, controls and dryer + the complete vintage air front runner 6 rib serpentine system with powersteering and alternator and AC and was cheap also all never used.

    As for the install; if you can go with the sure fit it comes with everything, if you need space like I do for my new computer then you can get the GEN II Compact; It should be about 600 with AC, condenser, dryer, controls, main unit, firewall plate and extra parts for the ducts.

    You might be able to use the old AC setup and belt drive if you convert to R134.

    Great info melo. Thanks.
    P.s. I converted to R134 many years ago. It worked decent, but those components, hoses, etc are all old. Tired of chasing leaks. I could spend $600 on a new compressor, hoses, and evap. Not only that - I would love to clean up that firewall!!

    Looking forward to your progress pics.

    Moving slowly but surely ... I started to close up the interior, remove parts and paint them plus remove the old vent (I will post pictures of that next):

    I had to remove the vent from the passenger side kick panel.

    To do that first, I used a dremal to cut around the vent:
    [​IMG]

    Here is the fully cut vent:
    [​IMG]

    Here is the back side of the kick panel:
    [​IMG]

    All nice and painted:
    [​IMG]

    I had to remove the rocker covers they were horribly rusted:
    [​IMG]

    You need to cut to fit these rocker covers:
    [​IMG]

    Here are them installed:
    [​IMG]

    While there I touched up all of the panels:

    It looked like you removed/cut , the wire cover thing, and part of the inner rocker, or are they one piece? and don't you have to weld that back? Your painting looks better then mine , did you use SEM paint, and there plastic paint promoter? Looks great, looks like there will be lots of extra room. Sorry, forgot to ask , why did you need to dremel out the vent?
    Thanks
