And to make things worse Larry, not all convertors use XLV in their naming scheme.

For example the XLII models. This does not mean it is a 42' bus, it is the type of bus, a Non Rivet coach with a newer modified front cap. There are 40' and 45' XLII's out there. More of the 45' units are in the market than the 40' but they can be found.

Keep asking, there are many more questions as well as answers.
