If you don’t find some, I also recommend Pine Tree Audio.
I would measure the center to center (edge to far edge is the same as center to center), and the gap between them, in MMs
right angle adapters can let you use cables you already have, they rotate on the jack to allow different entry angles for adjacent cables, and if needed you can grind/file an edge so they fit side by side.
These are metal, plastic covered ones would be easier to shave a corner/modify if needed.

Amazon, order a few that look like they might work, keep one, return the rest
