Never used that one, but the bracket for the 55-56 factory a/c will work with the Sanden type compressors and will work with a single belt that also drives the generator and fan, so need for a multi-groove pulley.  Wonder how many of those bracket you threw away?:P

LOL  of all the 20+ Buicks that have run through my hands, only one had factory A/C.  It didn't have the original engine though and compressor and bracket were no where to be found.  A forum member has all the other A/C parts off that car 🙂

This compressor, pully, and bracket stuff has been on my mind for years.  I have two cars:

 

First: A 1958 41 series (non factory AC).  Replaced the 364 (still have it with matching VIN but not rebuilt) with a rebuilt 401 with 59 factory AC setup on the engine only.  Takes an A5 Sealed compressor as bolt-in.  Will use an underdash unit.

 

Second, being built, is a 58 Century Convertible built in California no AC.  58 364 low mileage engine which I do not intent to rebuild at this point, got all the pulleys and brackets again but this time for a factory AC setup, engine only.  Will also use an underdash unit.

 

What is the best way to get a compressor into these?  What Sanden model.  I am willing to modify factory brackets.  Or fabricate.  But I don't know nor have done the research as to what Sanden to use.

 

Considered using A6.  Someone makes one which will bolt into a Cadillac as a replacement for an A5, but I don't think that would work out very well.

 

From the beginning of this journey to putting AC into these old cars, I figured I would be better starting with factory AC setups as far as the engine.  These things changed every year and there are many variables involved in getting it right.

Capgage,

 

With the size of your car and the amount of glass in it, I would go with the Sanden Series SD-709.   It pumps 9.5 cubic inches per revolution with a maximum 6000 sustained RPM range. This is what you need on a Nailhead with the large cabin space. I am in the middle of putting the same compressor on my 60 Electra for the same reason.

 

If you want an A5 I have one from a Cadillac.  No idea if it works or how well it works. It still turns last time I checked.

Bill,

 

Thanks so much for sharing that.  Now I have a starting point for Sanden.  I guess I'll have to buy one and then see what mods I can do to the factory compressor brackets to make it fit.  To start with toward getting my after market AC unit to work.

 

Did your 60 use a sealed A5?  Or an A6?  If it used an A5, how does your Sanden work out with the factory AC brackets?

I use a sealed A5 and a Powergen Alternator.  I am not sure how it is going to work yet, we are still getting the unit inside the car installed. 

Ask again in a month or so and I will have a much better idea.

 

Have you looked at http://centervilleautorepair.com ?  They have brackets that may fit what you need.

RivNut is correct. The Allan Grove stuff tries to move all the moving parts "up and in" because of the way the nose on early cars pinch in. I wanted a clean look with lower components and we moved the brake booster to the trunk to make room. I am fitting a Vintage Air compressor, alternator, and power steering pump in a '37 Special with a 401 all while using a modified stock radiator and keep the stock 401 fan.

What vehicles used the Sanden sd-709 ac comppresor originally?
