The WarBRD, the CM-2, and the CM-3 all bolt to the universal baseplate.
The first 2 bases have the indent for the XS-9 connectors. The CM-3 doesn't have the indent, but the length and width are the same.
TPR's were available locally, so I went with those. Happy to upgrade from 10 year old Saiteks. Ended up building a whole new sim around the pedals.
I removed the baseplate to mount the pedals into my rig. Dropped them just enough I can go full-foot or just use my toes.
