If the OP wants an alloy CSX, there are a few coming into Shelby inventory via Kirkham in the near term (this year). I think fiberglass cars are into 2023 now.

Prices, as well, are rapidly escalating. Several recent price increases.

From my reading of the thread about the KMS differential, it seems that the KMS differential is an option for both CSX continuation cars (aluminum or fiberglass) as well as for the Superformance cars. The option is obviously not called the KMS differential when you order the car, it is probably called something like the optional alumunium differential. It seems that if you pick that optional differential that you want to make sure it is installed correctly to make sure it does not self destruct.

It seems that some aluminum CSX cars are complete Kirkham rollers from Utah, you do not need to worry about those because Kirkham will obviously install their differential correctly. Other alumimum CSX cars can start off as a Kirkham body/frame with most other assemby in Africa. Fiberglass CSX cars are also mostly assembled in Africa too. So if you order the optional differential, you should definitely make sure that it was installed correctly, because it seems that SAI, Hi-Tech, Hillbank or whoever have installed the optional differential in such a way that it dumps all of the fluid on the street as you drive. Maybe by now they have learned to install the optional differential correctly, but I would not count on it.

The differential thread started in 2017. And yet it continued.

Did they learn to install the differential correctly by 2019? KMS Differential Questions (this link starts at post 1461140) I will give you a hint, the answer is NO.

Did they learn to install the differential correctly by 2020? KMS Differential Questions (this link starts at post 1485154) I will give you a hint, the answer is NO.
