Euro Conversion Tool for 3.60

Does anyone can help me out with subject? We have customer running 3.60 and there is need to convert to EUR.
Please do not advise Navision upgrade to 2009 or Conversion Tool downgrade from 4.0 - I know theses options, however they both seem to be very very painful for this customer. [:S]

If you have this tool please drop me a message.
