Does my 2001 have a CDL?
The SLABS from any '03 or '04 DII are upgrades that work better with a functioning CDL. The Holy Grail SLABS is SRD500070. I got the SLABS for my truck out of an '04, and when I removed I found it was an SRD100050. Both work fine with a functioning CDL.
As for SLS or non-SLS compatibility, there are no different part numbers. Any DII SLABS can have the SLS setting toggled between air springs and coils. If your truck has coil springs in the rear you'll want to confirm the SLABS is set for coils. If your truck had air springs originally and the SLABS is configured for them it can drain the battery trying to run the compressor to adjust the ride height, even with the truck turned off.

I used the Ashcroft mechanical linkage from Lucky8 on my '00 Disco. I like the fact that it is a mechanical, "push the lever to engage". My concern was the electronic demons that sometime plague our Discos. It's nice to just grab the lever and go into lock.
Personal preference.

I don't recall how many '04s I've found in boneyards and looked for a 500070 without finding one. Between my post in August and now I pulled the SLABS from yet another '04 to and found it to be a 100050. I didn't think to look at the build date on the door sticker.
If you can't source a 500070 just go ahead with a 100050. It has the most important updates and has worked just fine in my truck.
I don't know of any documentation available to us about the differences between the 100050 and the 500070. I expect that the 500070 is the Holy Grail only because it was the final version, and presumably has a tweak or two vs. the 100050.

I was wondering though, is the 500070 the best because it was the last? How were you able to make this determination?
Also, I want to see which one I have in both of my ‘04s (you have me not confident I’ve got the Holy Grail ones, but would like to know). Is the only way to pull the glove box and take a gander?
I think this is a very important discussion in terms of proving just how good a D2 can be out of the box.

Doing some quick research, I think this helps explain it a bit:
