Random question time (must be being upside down that's affected my thinking?

Can someone please measure the length of the lower front cross member on a lude.
Ideally on a 3g, but a 4g would do.
Item 7 on here (this drawing from a 3g but 4g is similar)
Measurements across the front, to the outside of that specific beam.

Hoping it's under 105cm...
