I want to say its about $150 for everything new. If you have a good trans yoke the price drops quite a bit.

So you can see its really not worth it to drive around and buy a used shaft for $50 then spend another $100 having it shortened and ballanced, Assuming the weld yokes are useable.

I noticed somebody using an aluminum shaft, those are usually too large in diameter to use in a 2wd 67-72 and theirs no way id use one on a 4wd that ever sees dirt as many aluminum shafts are so thin you can dent them by standing on them. But they do look cool in a show truck.
I also wouldn't use aluminum for a drag car with slicks, because just like aluminum connecting rods they will flex and eventually become brittle and break, so they need to be replaced every season or so.

Remember when you change trans yokes on a driveshaft you should have the shaft re ballanced. Individual parts aren't ballanced and the machining process for where the ujoint is held isn't perfect, meaning the shaft will not run true and have a vibration. Ballancing the entire shaft as an assembly is the best way to prevent premature wear and failure of parts.
