ACE isn't selling anymore. Below is their email autoresponder. I got this when I emailed him some pictures of my ACE-swapped Disco on the trails in Colorado and Arkansas. He did reply to my email and thank me for sharing the pics, so he does check the account. I've not heard an exact reason why he stopped supplying kits but my guess is he got inundated with tech support questions and it was driving him mad. I had to email and call several times because his instructions weren't the best. They might have gotten better in later kits but mine was an early one and the instructions were rough.

 

If you're looking for a good Disco 2, I have a 2003 with 100k miles that I'd like to sell. The rear chassis legs are rusted pretty good... but the engine is solid and runs great. I've replaced the head gasket years ago with no problems since.
I am going to post this on the marketplace soon.. just haven't gotten around to it yet.

 

That sounds like the complete opposite of what the OP is looking for.
