A bit of an FYI:
I was vexed by how close the front belt ran to the included servo stay so I had a look through my parts box and can confirm:
Tamiya 53875 TA05 Lightweight Aluminium Servo Stay
Does the trick perfectly. You have to accept half-height stays but I'm pretty sure that won't be an issue.
The key here is that this pack has asymmetrical stays with a bevelled top surface so it falls comfortably under the belt. It's still close but the gap is increased about 200%.
Edit: also available in black
