Last version is here http://vstanced.com/page.php?id=1923 It's an old mod from 2014 by Mythbuster. EDIT : @Camera2004 You posted the old version...
Any chance you can update this evo? https://www.beamng.com/threads/2006-mitsubishi-evo-9-updated-5-25.33698/
I'll drop this broken russian mod here https://www.worldofmods.com/beamng/cars/2282-pontiac-firebird-trans-am-1977.html Maybe if you could rework on it!
Do you do jbeam fixes? Some of these old mods require updated jbeams. That Firebird above should go on a Barstow jbeam.
I tried fixing that firebird once but quickly realized to do a lot of older mods properly it needs a massive amount of work
