I'm installing a complete system from Classic Air in the 73 . The heater core started leaking last yr & the air has leaks . So I decided to upgrade to a new system. I've done this before in the 68 & apparently this is a better upgraded system. I'll see. It's really not that hard just labor involved . I won't be posting pics as it's all over the internet now. When I did the 68 10 yrs ago it was a new idea & you were pretty much on your own.

I just put in a new heater core just before you bought the car. That didn't last long at all..............jack

Yes it looks new, just goes to show it's hard to get good after market stuff these days. It'll be a breeze to work on & repair if needed with the new system. That old compressor really bogged the engine down too. The newer one  is hardly noticeable.

That was the second new one I put in there since I had the car.

Do they give you a parallel flow condenser with the kit? That seems to be the key when converting an older car with a serpentine flow to 134a............jack

I'm not sure I haven't got it yet. I'll check the 68 tomorrow. I know the condenser has to be bigger because R134 isn't as efficient as R12. That's why when you convert a stock system you don't get the low temps.

With the larger condenser will the R134 get the temps as cold as R12? Undecided

I think as long as you go with the parallel condenser the answer is yes. they are much more free flowing and efficient.

I did this upgrade on my 73. I replaced everything at the time except the controls.
I believe it works as well as the old system but without the high price of the R12.

what I meant is since you upgraded the '68 and are now tackling the '73 I was wondering if the '77 is on the radar, I remember when we took it to get checked by your A/C guy he said the system was intact but believed there was another cause for heat bypassing and not letting the car cool down as much as it could.
that's all I meant.

I installed a shut off valve on the 77. The air quit working so I'm still thinking, but I might just leave it alone to keep it original. If it's hot I can always take another one Wink If it doesn't sell I will pull the engine & go over it & bump it to around 300hp.

Well I got most of the inside done ...waiting on a radio. The only thing I see wrong is they should have applied or supplied heat shielding for the panel that cover the blower motor & heater box area. Other than that so far it's pretty straight forward . Some of the pic's & descriptions don't match the car, but that's understandable as this is for a 68-74  non air & air cars.

Every year I keep saying I'm going to get my A/C fixed.  Somehow I never do it.  Guess I enjoy driving with the tops off too much. Grin  If I wasn't keeping it original, I might look into this system.  Seems to be better than the OE and cheaper than fixing the OE. Cry

Maybe next year. HA! HA! HA!
