Cessna 150 flap travel

[Eric Brown]

Does anyone have knowledge of the physical differences in the Cessna 40 degree and 30 degree flap actuator assemblies ? The used assembly that I installed in my C150L has only enough travel to put the flaps to 30 degrees before and internal mechanical stop is hit. The mechanical stop is hit before it hits the down limit switch. The exposed jack screw is at 5" when it hits. Would anybody be able to measure their C150L/M or C172 L/M/N or C182P/Q full down flap exposed jack screw and tell me what you measure ????? Thanks
