Upgrading MK3S to MK4S carriage issue

Hi, 

I don’t have the same carriage than the one shown in the manual or video. The carriage hits the top of the Y motor holder ( but not the motor). Here is the picture? What’s the required solution? Thanks.

Did you read and follow the instructions carefully that can be found here?: https://help.prusa3d.com/guide/7-y-carriage-heatbed-assembly_600903#601470
It looks like you are missing the parts that are indicated by the blue, red, and yellow arrows on that page. So the carriage is too close to the rods.
