Replacement wipers

[five50]

I ordered some new Bosch wipers online from a windscreen wiper specialist.
I was sent 2x Bosch 16U wipers - I went to fit and then realised that the wipers on the car are not the same length.
One is the size of the 16U and one is longer.
The seam / lip running along the top of the factory wipers is slighly offset from centre - whereas the Bosch wipers have that central - not sure if it matters.
I can probably spend some time working it out, but for avoidance of doubt / speed, does anyone have the exact spec for replacement windscreen wipers?

As a Yorkshire skinflint I sourced replacement wiper rubbers from eBay, a much cheaper alternative and very easy to do. There is a thread on here, Volvo V60 MK2 are the ones you want.

Volvo V60, part number 31693570. Need cutting slightly to length but work perfectly.
