LDC specs for Duo-Phase

There are 12 LDR's in the new Duo-Phase project. But the BOM doesn't state what the specs for them should be. Most "Univibe" clones recommend the Silonex 7532 or 7530 which has a stated 6.7 Meg dark resistance. Also the 9203 which is listed as 5 - 20K light resistance, 20Meg dark. Used in several other "Vibe" designs.
The rest of the design used regular parts so that isn't an issue. I just don't want to buy 12 of the wrong LDR's
Thanks

I like the 9203s best, but others have had great results with the KE-10720 from Tayda, which is fairly close to the GL-5528 that can be had for pennies on Amazon

I stumbled on a selection method. Basically set one of them up, with an LED. Adjust until the LDR reads 1k, then check the others. Keep within 5% deviation until you have 12.
This does not help you in buying I guess. I got mine from Das Musikding in a kit and did not verify them yet.
