Download 0.18.3 ?

[Sardonyx]

Hello,

I just found this game on the Steam sale and I love it! My friend mentioned that if you purchase through the site they have older versions available and it's DRM free. So I went ahead and bought a copy on the KSP Store today too. There's only download links for 0.19.1 and 0.20.2. Is there a way to get a copy of 0.18.3? There's some space ship designs/mods from that version I'd like to play with. If not, is there a conversion program to bring them up to date?

Edit: I just realized the ships are built in 0.17 not 0.18.3! So that's the version I would actually need to test them.

Specifically I want to look at the Gallileo VI+ from StompThompson, but looking at the file it says 0.17 and the current version says it's not compatible.

Thanks!
