Frame Dimensions?

[smokeless]

I thought if I waited long enough I would see this discussed, but I couldn't wait any more. Does anyone know if the width(dimensions) of the frame on the X where the front down tube splits and goes under the case is the sames as on the 04 R? THe reason I ask, was I was going to check into using the overflow bottle that comes on the X for my R. The dealerships seem to know much less than the readers of this forum!!

Thanks for the help.
