I will add if you need to shorten the drive shaft the one from the van will work, the one from the car will not. Car drive shafts are double layered with a rubber layer in between. Van/truck drive shafts are all steel. I learned this 25 years ago when I took a drive shaft to be shortened.
Some are, not all. You can see the ones that are rubber insulated. They look like one tube slid inside another tube with a rubber ring in between. They were mostly on '66-7 automatics.
