Help Please Driveshaft ??

sup guys, the driveshaft has snapped on my extra cab 89 b2000.
have been ringing around trying to get a new one and they keep asking what spline it has? can anyone shed some light on this also is the driveshaft 3 piece?
sorry for the dumb questions any driveshaft info greatly appreciated! cheers

well how many joints does it have in it?............ the splines are the teeth on the end that go into the trans... pull it and count the teeth
