Yeah, I can't believe I forgot to check them. I was going down the list of 
suppliers I use and I totally forgot them.  Thanks for reminding me.

And yes, replacing the expansion valve on a W126 is a real PITA, so I've heard. 
There are some good DIYs for it on Benzworld. According to some, removing the 
safety bar or reinforcement that is nearby makes it much easier.  Looks like I 
might need to get some metric crows foot wrenches, too.

I don't want to go to this much effort and expense and not swap out the 
expansion valve on the off chance it's crudded up, either from this failure or 
just age and the conversion from R12 to R134a, whenever that took place.

Got the confirmation on the two pass condenser a little while ago. Looks like 
it will ship tomorrow.
