Might be worth getting some measurements and hitting the wrecking yard for a driveline. I don't know if they all do this,but Pick-n-Pull in Reno has a whole rack of drivelines;you just check measurements until you find one you can use,stop at the parts store to get the u-joints you need to match up the ends to the yokes and you're in business.
