Hi,
If you have a Gran Sport, Dan is correct, if you have a Skylark or Special Deluxe, the fender spears are die cast and believe there is 3 or 4 nuts that have to be removed.
You might be able to get them off by removing the inner fenders, either way you will need to remove the lower fender mounting bolts (2/side) to slip out the inners, also works for removing the heater core.
Regards,
