I think the hard thing to find would be a nicer one. I have one laying in my garage that I took off a parts car when I awd swapped mine. The only part I used was the rear section. You could maybe go with a driveshaft shop one. At least it would be new.
You could also try Stevie from Miller import parts for a used one.
