Speedo Cable to Trans, remove how? 79, EA81 wagon 4WD, 4sp dual range manual transmission.
The Speedometer Cable has a rubber/plastic boot which I have slid upward to expose a ~1/2 diameter collar then a hex fitting which a 17mm fits onto loosely. the 17 mm hex is about 1" long and seems to be made of plastic although it's blacked by crud and doesn't seem to clean up with penetrating spray.
When I turn the 17mm Hex counterclockwise as viewed from above it seems to flex but NOT UNSCREW.
If it's plastic I may break it or strip any plastic threads going into the transmission.
How does the cable come out??
