Most often, wheelbase is the dimension from the center point at the end of the front axle or spindle to the center point of the end of the rear axle.  Note that the measurement could also be described as being between the center points of the circles described by the front and rear wheels on the same side of the vehicle.

Track is the dimension from the centerline of the tire tread on one tire to the centerline of the tire tread on the opposite tire on the same end of the vehicle. E.G.: Front track or rear track.  On vehicles with dual wheels, that measurement is commonly taken from halfway between the centers of each tire on both right and left sides.  There are also "Inner track" and "Outer track" dimensions, measured from the center lines of the inner pair and the outer pair of the dual wheel axle.

The second section will be listed as axle flange to axle flange where the wheel bolts on. Drum to drum would be close enough to the same if that's all the information you have to post. The only difference between the two would be the thickness of the material of the two drums or brake rotors/discs at the studs.
