4 legged trimpots for minimoog

Hi all - I'm currently attempting to clone a minimoog, and trying to keep as close as possible to the original circuit layout. I'm trying to track down trimpots similar to  http://www.surplussales.com/Potentiometers/PCM-SlotAdj/PCM-SlotAdj-1.html (part number (RWV) 137-8446 on this)

10k, 1k and 500R are down- but I'm searching for 100R, and 25R.  Does anyone make that 4 leg footprint anymore?  Cheers, Jim
