Why would a '69 LCS A/C take a few miles to start cooling?

MFE. We removed the compressor and receiver dryer and sent the both out for rebuild to Classic. They had the repro expansion valve. it is a 1 or 2 year valve.

What do you mean, 1- or 2-year valve, Rob? Does that mean it needs to be changed out every 1 or 2 years as a maintenance item?
Well, yesterday, I finally did what I've been wanting to do; I bought one of those brand-new evaporators for Frankenstein. That ought to leave only reproduced lines to be had, aside from R-12 stock which is out of my league. Now, if only I can get the engine to fire up again...

Tony,
The expansion valve on the 66 was a 1 or 2 year valve. Very difficult to find. This is what it looks like in and out ports are horizontal

Classique has it also..Go to expansion valves and you will see the difference in valves/years... https://www.classiquecars.com/lincolnaircondcart.htm

Oh, okay! Now I know what you meant: Its design was used for only one or two years of application. Sorry, I read it wrong; I thought you meant that it was a maintenance item requiring replacement every one or two years. Well, I was able to find that exact design of expansion valve on E-Bay, from a seller other than the ones cited above. It's been a few years since I got it, so I can't remember who it was; but I know that listing is still active because I never removed it from my watch list.
On another note, I got my new evaporator core today, and it looks great! I compared it with the OE evaporator I have stashed away, and it will be an exact fit for sure. It's constructed entirely of aluminum, as opposed to brass and copper with aluminum fins like the original, so it's noticeably lighter, I'd say by about a pound. I noticed a few slight differences in the core itself, but they are minor and should have no adverse effect on the system, nor in installation. The shape and all the mountings are exactly the same as the original*, so now we Suicide owners of the latter half of the decade have new evaporator cores to be had when needed!
And now, apologies to MFE for hijacking. How is the progress of your issue, MFE?

* Update on that claim: The mount points are not "exactly" the same. The lower mount bracket of the new core has a right-angle edge which will jam against the firewall. The lower mount bracket of the original core has an angled edge, to conform with the firewall contour at that spot. Luckily, it is an easy mod to cut an angle into the new core's bracket to make it fit...but anyone who also must replace their cores must be aware of this. You will need to modify the new core's lower mount bracket for the core to fit in the cavity properly.

Whatever happened with the original question? Did the problem get repaired?
