added note to the above post.
The car currently has a non A/C upper radiator hose. Me thinks an A/C upper hose may provide additional clearance. Anybody know this? |

Since my 71 stuff did not use O-rings, I think instead of converting to 74 dryer / Condenser, I may just do the reverse on new hoses by welding on old style heads to the dryer and Evap hose ends. Unless 74 on up dryers are easier to come by for replacement.
It is nice to know the hard parts stand up to R134A without failure. I guess once you start putting things together for fit and finish, exact parts may be different especially for year and model, let alone how one wants to arrange hoses and fitment.

My Javelin is a 70 Donohue and my father bought it used 1 year old in 1971 so I guess I am the 3rd owner. It has been licensed it's entire life although at times parked extensively. It is at best a survivor and as such has been wrecked once, blown up twice and the OEM 4 speed was replaced with a T5 when the transmission went out in about 1994 or so. The A/C conversion was started and not finished (yet) due to my back going out. It is a Vintage Air under dash install with an OEM Compressor mount and a York to Sanden adapter to get the Vintage Air Sanden compressor mounted. There are no clearance issues using 1970 OEM compressor mounting hardware. I just do not have the back side mounting bracket hardware and so few 1970 vehicles ever had OEM AC I can not remember seeing one. Most 1970 Vehicles collected are either pony or economy models such as a Gremlin or Hornet. And muscle conversions were done with out AC.
I have a Late Eagle mounting bracket for a Sanden compressor but my Spirit which has A/C was put together using a York compressor and has worked so satisfactorily over the years I have never bothered converting it. So while I have the parts on the shelves (I am trying to clean out and clear out of the garage) I'll probably never use it. My Spirit has been a very satisfying car to own, a modified 258 runs like a raped ape and is on the road quick, with a short wheel base and a suspension similar to a 70 AMX with large road tires is more than a pleasure to drive. I dunno, it just seems to me that AMC made some pretty neat cars in the 70's that were horrendously marketed but that is personal preference speaking. They had FI running according to people I know who worked in AMC at the time (Rennix system) and did not install it at a period in time that might have made a big difference in the cars that would have sold and didn't. Wudda/Cudda/Shooda I guess. I am installing the AM-Air Dealer installed under dash AC in the Hornet I am putting together using a GM "Muffin" compressor mounted on the Mercury Marine 5.7L V8 I am using to power it with conversion parts from Vintage Air where needed to use the flared fittings that came with the piece. I am hoping everything will work well. It is not together yet. All I have to do is hook the wiring up and verify tightness of the fittings, but getting the car actually painted and the wheels and tires chosen to fit has been a priority. |

On the VA unit what one did you go with? You said under dash is it under or behind like stock? Also do you have a post on this install? |

V.A. has a number of period designed (cosmetic) cases that fit under the dash. The works or what makes it cool things does not appear to me anyway of being something unique as in appearances it is similar to the 1976 Vintage AM Air unit I am re-installing in my Hornet. An originally dealer installed package. Of course updated in materials and such as far as the working mechanisms are. And under dash unit does not vent out side air to be cooled, it recycles cabin air and frankly there is nothing really wrong with that. On todays new cars that is a push button option that not only recycles cabin air but jacks the motor speed up also. It is used for rapid cool down of a hot car. What I did was to measure available space under the dash on the passenger side of the car as on the Pony cars there is no room between the dash and the transmission tunnel and as they are cosmetically period correct to the 70's it looks pretty good. It came with bulk hose material, pieces to make the hoses, parts to run them through the firewall and a Sanden compressor as Vintage Air has no or did not at the time have engine kits for an AMC engine and I choose the size of the condenser that mounts in front of the radiator. What is needed then is a method to mount the compressor on the engine and run belts to it and I was able to purchase from people and vendors the AMC mounting parts for a York style compressor and an adapter for a York to Sanden compressor. No, I have no information on mounting it. The project got set to one side when my back started acting up and I hve not finished it. You have to hang the underdash unit, make holes for drains, run the wiring and hoses and mount the hardware on the engine. It is pretty straight forward In the mean time I have been working on my Hornet Sportabout which will use an AM/Air dealer installed underdash unit with a Mercury Marine engine which uses Chevy Small back accessory mounting, a muffin compressor with Vintage Air adapters to match hoses from compressor to 1976 Vintage underdash hardware and run wiring. I have gotten spoiled in my old age, I like a fast street car with A/C. So I see to it when I build something it is A/C equipped. |

[/QUOTE] I know what the dealer installed Hornet/Gremlin unit looks like, but on the 70 Javelin under dash, I assume it hangs on the passenger side only?[/QUOTE] Correct. As stated, there is no room between the dash board and the transmission tunnel for anything else. In addition, while there may be an exception, I have never seen an aftermarket under dash unit except those that were uniquely designed cosmetically to fit across the full length of the dashboard and then those were designed uniquely to fit Hornets and Gremlins that did anything else other than hang down from the passenger side of the dashboard. V.A. had I think three different underdash units in their catalog when I ordered mine. I took measurements of my dashboard and compared to dimensions given in the catalog and ordered the one that fit my dimensions. Think about it. Where else would one go, there is no room up inside the dash board to fit a generic aftermarket unit. And V.A. does not offer or did not anyway at the time I ordered my package an in dash design that would fit an AMC car. Those were only available for the more commonly built shoe box cars of the period and assumed a full dashboard rebuild anyway with an engine kit. (The engine kit was also no available. The engine kit being mounting brackets and drive pulleys) |

Thanks John I thought you replaced the stock heater box unit with a VA unit but see you went with an under dash unit.
I did not really want an under dash unit but will look at them. As for the compressor mounting side I did have a York bracket if it came with me on my move and for pulleys Bulltear may get a call for their belt kit for some bling Thanks again. Dave ---- |
