Mark,
Here's the info to the FB site and post, by George V, March 24th 2020. It's a bit of a scroll but all the comments and interested parties are there.
Group is Audi RS6 Builds and Performance, lots of good info and not just people posting pics of the new cars.
Hmmm, if he's not going to make Automatic specific radiators I might be out, didn't realize that. I would assume they could do the fab work in house to make them ready for an automatic before shipping out if interested in making the sales.
