How to get other versions of Beamng?

So I know you can click the manage and properties and change the beta, but the version i want to play (the first version i played, 0.20) isnt there, are there any other ways to play the other versions? If not its comepletley fine i can just use the 0.23 version they have, but I just want to nostalgia trip XD. If you took the time out of your day to actually read this, thank you.

 

Someone else on the forums sent this that seems to work: https://steamcommunity.com/sharedfiles/filedetails/?id=889624474

 

Yes you can do it by this way.
Otherwise, giving a direct download link is piracy.

 

Thank you!
