What PN is that ?

Volvo PN 30699847 has been superceded by PN 31333470
How long is your blade ?
3470 - middle stud mount to blade arm length , it is 14"
In looking at where it bends, offset on tension, looks like 16" is a good length.

Another post in that other thread had a XC60, with a different PN of 31333448
