Stepper motor length spec question

Hi,

I am trying to source the steppers needed and want to make sure I am looking at the right spec.
On the BOM it says 4   -   Nema 17 stepper motors (max length of 40mm recommended)
When referring to the max length of 40mm are we talking with the shaft? Or just the length of body?

What shaft length would be reccomended if it is body length only?

Thank you,

I am referring to the length of the motor body.

The shaft can be either 4mm or 5mm diameter and both 15mm long and 22mm long shafts have been used.

Is there a recommended part# for the stepper motors, or spec (torque, resistance, step size, etc.), or... what stepper did you ship with the kits?
I have some steppers handy from Lin, 4218L-01-11, but they are too long, at ~47mm body length. I assume since it's standard reprap electronics that the usual recommended steppers are fine, just wanted to make sure.

Sorry for not answering earlier I just became a dad a few days ago and things have been crazy.

I used 42BYGHW with the kits. Any of the recommended RepRap steppers will work fine as long as they are less than 40mm long.
