Doepfer Dark Energy Glide Option

Hey all! I recently acquired a Doepfer Dark Energy from 2010 but it has no glide option installed. It is essentially a 10m log pot with a pair of jumpers on the end that that works with all 3 dark energy models. Was hoping to buy this glide option somewhere but can’t find it anywhere, which is really weird to me because the Dark Energy 3 is only 4 years old! Can anyone point me to where I could grab this part? Here’s a link to a discontinued listing for reference.
