Third from left photo shows a different and neater solution to the set up that was on my 411. On My car the compressor sat in the position of the alternator in that photograph. One of the things to bear in mind on trying to set this up is that all sorts of mounting brackets and drive belts were used over the years and it would be better to try and find a solution that worked in period for Chrysler rather than what Bristol did originally, I may be wrong but I doubt any US car had the same AC compressor fitted that Bristol used.
A trip to a breaker dealing in older US cars may pay dividends and ordering what you need directly from the states could save you quite a bit of money now Bristol Cars are no longer around to help.

Thank you Xseries unfortunately the photo to the right is a 411 but is fitted
with a later smaller block motor. The middle photo I am not sure what motor it is, note the dip stick is not in the correct place for a 383. The left photo gives some small idea as to where it is mounted.The choice of compressors isnt easy as most modern compact units would be ideal but come with the wrong pully. The best I have found so far is off an Early Toyota Hi Lux. This could easily be mounted near the alternator and move the alternator to a position near the fuel pump but so far I havnt found one small enough to fit.

Geoff if your compressor was mounted where the alternator is shown where was your alternator moved too?

Peter,
It is on the right hand side of the engine viewed from the front with the power steering pump below it.
Geoff.

The two photographs with a compressor in place are actually of my 603E with the 5.2 engine, the other photograph is of the 411 showing the position of the alternator almost directly above the power steering pump.
There would also have been a pump on the engine for the self levelling but that had been removed before I bought the car.
Geoff.

Here are some pictures of the first AC installation on my 411. The (Denso) compressor is where the alternator was originally and the alternator has been moved to the where the self leveling pump was.


As you can see the condenser was in front of the radiator. The AC worked well, but the engine ran very hot (to hot) on warm days, this was alleviated a little by installing a large electric fan on the back of the radiator, to pull air through, but the engine cooling was still marginal.


Unfortunately the original two electric fans mounted in a cowling in front of the radiator was not a very effective setup.
