I have a 2001 Pontiac Montana SW. I assume the SW means short wheelbase. Is the wheelbase 112 or 120 inches in length?

Wheelbase is the distance from center of front wheel to center of rear wheel.Tape measure

  • Make sure the front wheels are straight when measuring.

  • That's a nice measuring tape. Good resolution. Nice contrast between the faux chrome and the yellow. All in all, very nice balance. +1 Commented May 13, 2016 at 18:21
