Good question I’m not sure off hand but I’m like 99% sure you can get them from their website under schematics. If you don’t get a reply soon I’d def just call their technicians department it’s usually not a wait and those dudes are on point with info haha.

they just have part numbers. i asked i a forum in facebook an the thread size is M13x1
