Your inbox was full but heres my reply:
NO prob. I just wanted you to know there was a nice one for sale in my neck of the woods. I didnt know what you were loooking to spend. If you were to not use the glycol system its not a huge deal. Most of these set ups have SSteel tubes to the bottom of the tower and require a beer line to either go over the tube or have fittings to do so. To your other question I'm not sure but it sounds like they may have gotten another tower the same (Base) and will go in the same place as the old.
I'd ask the seller about in an email and they may be able to give the new one that came with the newer tower...
