Where are the Unity 4.6.0 standard assets ?

Where can I find standard assets for Unity 4.6.0 to download? They have been removed from the asset store and only the assets for Unity 5 exist. I do not wish to upgrade because I like unity 4 and the tools and resources for Unity 4 are sufficient for my needs.
To be precise, I only need the vehicle, aircraft and boat physics in those assets, so alternatively, I would like to find free vehicle physics packages to download for Unity 4, I could only find packages for Unity 5, 2017 and 2018.

 

It hasn't been "removed" from the store, it was deprecated. That means if you have ever downloaded it from the store on your account before, you can go to your list of store assets and download it again.
