Hawk Wiper Arm and Blade

[hollytree]

... I struggled to find a Citroen arm and have bought one of these Exalto LD Wiper Arm 330-450mm | Force 4 Chandlery it has a pinch bolt to work with the normal splines rather than a bolt through the splines so should I hope work with the normal wiper spindle.

Thanks
Do you think a drill bit could be run through between the teeth that grip the spines so the top nut on the spindle could then be used again.

Should this info be posted in the alternative build parts section
