Yeah that thread appears to be gone. I'm guessing that along with the Mods the OP has the option to delete the thread. I know it works that way on other forums, just not sure on this one. I initially was hoping for a response, but at this point it's moot. Duiser was selling their 4BT converted 80 with the NV4500 on Ebay. I had the wife convinced to let me bid on it. I'm very glad I discovered this thread and other postings by Phil. Those postings coupled with the fact the Duiser (Shawn) was being a little vague when asked about more photos/details convinced me to not touch that thing with a 10 foot pole. My plan was to hopefully fly out to Oregon to buy it and drive it home 2500 miles. Guess I'll just have to talk her into letting me build my own.
