Juliet November was asking about the DC-10 to MD-10 conversions. Below is a link to Boeing which has all of the specs on the conversions. I saw a press release about a year ago that FEDEX had ordered 75 or so of these conversions. I have note heard anything more about the conversions recently. The DC-10s do seem to be disappearing pretty quickly from the US passenger fleets.
I hope the info is useful.
