RGM folding kickstart measurement

I'm considering getting an RGM folding kickstart lever but don't know if it will work with my home made rear sets. I was wondering if someone might provide me with a measurement. I need to know what the distance is with the arm folded out in the kicking position, from the face of the gearbox just above the K.S. shaft to the outside surface of the arm. Thanks.

may be not what you need , but who knows ??

75mm folded out, 40mm folded in.

I copied the NYC rearsets and ran a bar behind the kickstart with plenty of clearance. You have to place the pegs further back than normal rearsets so your toes clear the kickstart.
