So this old mod just got revived, Dave fixed the link yesterday and I've gotten to play around with it. My biggest gripe is the engines, the stock SLRR V8's are terrible and make no sense, being DOHC and having no upgrade paths apart from mixing stock parts. Which is why I thought of adapting those 3 packs to this, but I have absolutely no knowledge of scripting. So this is why this thread exists.
Is anyone able to do this? I doubt it would take much of any work, assuming they work on 2.2.1 in the first place.
