Rich,
Haven't installed mine yet (son has car). I don't mind going to Ace for the lock nuts, but unsure what to get. By "all metal lock nut" do you mean the type that have deformed threads on one end, usually from swaged dimples in the nut, or do you mean a spring type lock washer? The deformed nuts might be hard to find in metric. Do you have an Ace Hardware PN or what tray to look in?

Yes the deformed all metal lock nut. You will need the M12 and 8- 3/8 24 if you have the Gen 2, only 4- 3/8 24 nuts if you have Gen 1. You could get by with just using all metal lock nuts on the compressor to plate bolts, as the others are not subject to as much heat.

Rich,

I finally had my bracket installed yesterday. My mechanic was very impressed with your bracket. He seems to think that my "Sanden bracket problems" are over.

For those who don't know my story, approximately 3 years ago, I decided that I wanted a Sanden compressor on my 1985 W123. I found a guy on eBay who was selling 2 CD's describing how to install his custom made Sanden bracket and also how to install a parallel flow condenser on a W123. I did an internet search but could find no other source of this type of bracket. Rather than take a chance on having someone else screw up the installation, I decided to drive all the way from North Carolina to Arizona to have the installation done by the "W123 expert."

The parallel flow condenser worked out fine but after installing his custom bracket the expert informed me that one of the ears of the Sanden broke off but "it wouldn't be a problem since 3 bolts would be sufficient." Everything seemed fine after the installation and I made it back home with no issues. A/C was ice cold. Then, a few months later, I heard a rattle and took the car to my mechanic. It seemed that the expert's bracket broke and required re-welding. My mechanic stated that, in his opinion, the bracket design was poor. Over the last 3 years, I have made six trips to my shop to have this bracket re-welded. I hesitated to take the car on any long trips, since I had now way of knowing when a problem would occur.

Finally, I found Jim's bracket on this thread. I am hoping that my nightmare is finally over. I am going to try to attach some photos of the retired bracket. In hindsight, I feel that the broken ear my have contributed to the problem. It may have caused increased vibration.

Thanks again, Jim.
