1970 AC condenser installed in a 66

Looks like I may need to remove the lower flange at the base of the core support to get the 70 condenser to fit in my 66.  Wasn’t planning on any more cutting on the project.  Ugh

Mixing in parts from different cars (I'm president of that club) always requires extra fun.

When I ordered the AC from CAA and mentioned I had upgraded the radiator to the 24 inch radiator, then they suggested installing the 70 condenser.  I figured I would have a better working AC so why not.  Lol

Re: 1970 AC condenser installed in a 66

By chance, could you share the condenser size?

Re: 1970 AC condenser installed in a 66

CAA did not consider the fact that it won’t fit.  The 7” has a huge recessed area for it to fit into.

But, I guess anything can be done…

On the other hand, there are condensers that fit perfectly in a 65-66 without undue effort.

Let us know how it turns out. Maybe you are onto something. A larger condenser does help.

It looks like I may only have to trim the metal that is vertical on the base of the core support opening.  But that may be just my wishful thinking.  I know a simple 1x1 section removed the this area of the core support will be more than enough to get it to fit.  This approach would allow me to use the supplied upper bracket like it was intended to be used. It may be easier to just make brackets that mount to the outer part of the condenser for the top mounts. This would avoid any interference with the 24” upper radiator mounting bracket.

I’ll make sure to get detailed pictures of all of this as I work it out.

Re: 1970 AC condenser installed in a 66

Got the condenser mounted.  Since the every is backwards my lines are bent the wrong way. First I was able to mount the condenser without cutting anything on the core support.  The only thing I need to do is add two clearance notches so I can get to the two lower screws that hold the bottom of the condenser in place. I need to do this in order to be able to remove it without removing the front racing apron.  I’ll snap a picture of that when I get it done. Pretty sure the racing apron needs to have some clearance cut in to.  Will check it today.

The small line the goes to the canister had to be bent to get it to fit.  I think it turned out pretty good for doing this by hand. The elbow that comes from the canister and goes through the firewall is backwards since I’m on the pass side and not the drivers side. So it passes through the firewall a little lower than it would on the drivers side. The top elbow from the condenser also passes through a little higher than it would on the drivers side.  This actually isn’t to bad because it’s pretty spot on the height of the AC compressor. 

So far my biggest issue is with the lines coming off of the AC compressor.   If the ports on the AC compressor were opposite of what they are now, I would be in a good spot.  In the pictures you’ll see I need to either have custom lines made or some kind of riser.  I’ll look into some options this morning and I’ll call CAA on Monday.

Today I hope to perform the bench test setup and install the unit under the dash.  I’m thinking I may need straight fittings from the box and not the elbows they sent. The elbows were designed to have the lines run along the firewall, I need them to come out straight.

All of those ines are made for right side compressor mounting.

Yep but so far it’s working it pretty good.  Not happy with the gap between the condenser and radiator but we will see if it cools enough at idle.  I may end up blocking the openings next to the condenser and core support, forcing the air to go through the condenser instead of the air having an option of going around it. 

Mounting the unit under the dash is proving to be a task.  The bracket that attaches to bottom side of cowl is about an inch away from the cowl.    I wish CAA offered an elbow for the drain instead of a straight piece of hose.

Here's my setup. Wonder why my compressor manifold is different?

Re: 1970 AC condenser installed in a 66

What’s the part number of the manifold?   I was suppose to get one that was specifically for the CVF compressor.   I paid extra for it.  If I’m looking at my receipt correctly I should have gotten 14-2702

Looks like compressor is clocked wrong.

I had Blueprint Engines order and install mine.
The link below shows the one they ordered for me, and the third picture shows the manifold that I have.

It’s been a while since I mounted it but it looks just like KieithP in his picture.  Even if I was to clock it more which would most likely have to be CCW, then my lines would be pointing down and I think that would make routing the lines even harder for me. 

I should mention that climbing in and out of a car with a roll bar that has door bars added to it is no fun.  I got a workout today climbing in and out of that car all day.

Re: 1970 AC condenser installed in a 66



Here is a picture of my dual fan setup. I had to remove that decorative piece on the CVF tensioner setup in order to clear the fan motor. I think removing that cover game me about 1/2" extra clearance. All I really needed was less than 1/4". I should contact CVF because they could easily machine that off.

Seeing how my condenser is not as close the radiator as I would like, I think a dual fan will be a good option for.  I’ll remove my cover and measure the clearance I have.  If it can be machined down.   Then I could see if one of my friends back in Ohio can machine it for me.
