My drivers side wiper arm failed, it basically had no resistance so you could swish it side to side by hand. Removed the arm and found it had worn away most of the splines in the arm... ok, no problem, order a new pair from ICP...

got these today

Thing is, these new arms dont have any splines at all, just smooth. I didn't twig from the description, i just saw they fit JDM classics.

Am I missing something here ??

 

Sorted.... apparently they cut their own splines as you tighten them down.. makes sense I suppose.
