D1's use 18inch blades, while a D2 uses 21inch blades. Simply just slap on some 21's when you get yourself some D1 arms and you're good to go.

 

Thank you sir.
I got new D1 arms from Lucky8 a couple months ago.
They fit and work great, but I didn't measure the new blades
I'll try the 21" ones next.

 

On the advice of Kernow Discovery I changed my D2 uplift wipers to new D1 wiper arms and aero blades, what a difference, the hooked type wiper arms as opposed to the clip type opens up a plethora of choice in wiper blades and types. They don't look as 'snazzy' as the original wiper arms but who cares, they work properly.

 

Sixpack, the blades are 21" or 530mm long.

 

For the 21" Bosch Icon blades on a D2 with D1 arms, do people use 1 A and 1 B? Or two A's?

 

I looked at the A/B's and couldn't honestly see the difference from outside the package. If I remember correctly I went with the A's.

 

Thanks as always. I ordered two As.

Also, what do people use for the rear blade if you don’t swap to a D1 arm there? Amazon says Bosch H351 but that doesn’t fit. On the first page someone mentions just swapping the blade. Is that the best route?

Rear wiper blade is about $6
