Hello,

I just purchased two replacement bosch aerotwins BBA650 and BBA450. When I filled the BBA650 it's perfect but the BBA450 appears to be too long and hitting the outside seal of the window.

I measured the wiper that came off and it is 430ish... So looks like BBA450 is the wrong size but when I checked the Bosch website 450mm is the correct size?

I have read on the forum that maybe the BBA400 is better suited?

Just want to find out what everyone else is using before I go out and buy a BBA400 to have another issue.

Thanks everyone for your time.
