How to use Wheeled Vehicle class in 5.1

Hi, I have a project made with an older version of UE and one class used in all blueprints was a Wheeled Vehicle class. Now when I open the project in 5.1, all blueprints are broken because of that. How can I fix this? I see that class is no longer in the engine, but is there any way to copy it ? Thankyou very much !
