These two items are supposed to be compatible, but I measure 16.9mm between the servo mounting tabs and the wires, but 19.1mm on the narrowest part of the bracket. Did a batch come in that were slightly off? I can’t find a dimensioned drawing to reference but I don’t think these go together.
The height and depth are a great match, but this 6001HB doesn’t fit in the bracket without damaging the wires. I can send pics if needed to clarify where the bracket and servo do not fit together.
