Big Huge Leak in AC, need parts advice

[Dieseldoofus]

I finally got around to putting a belt on the compressor on my '83 300SD as it was missing at the time of purchase. To check the function of the compressor (and see if the system holds pressure), I started the car and gave 12V to the compressor clutch. Well, it looks like good and bad news.

Good news: All of my ACC internals function, except for a few lights and a sticky blower relay, and now I have a working compressor.

Bad news: Refridgerant oil sprayed out the front of the car from a 1/16th in. hole in the removable hard elbow on the coil.

Now I know why there was no system pressure!

Is this something I can JB weld? My preliminary guess is that it's not but I'd love to hear a more seasoned MBer's view on the pressure at the point of the leak.

If not, is this a cheap part? I surely hope so.

On a side note, I'd like to thank anyone who has ever posted about removing the black box and associated EGR/Transmission control vacuum lines. Now the car has shifts like butter.
