Pvc pipe is length needed prop to prop, so minus 2 inches for the adapters and minus face to flange center line and then have the working joint to joint length.
The shaft on left is from a 01 or 02-04 isuzu rodeo and uses 1310 joints and has the slip, also in found in some ford rangers and explorers, need to find my paper that has which years and models.
Next is from a jeep grand cherokee, what it needs is take off bands holding the bellows, do not tear bellows, mark timing on splines, again need my sheet for accurate measurements, but then pull apart and take off roughly 1.5" from each, then put back together and attach bellows with acouple zip ties and install.
Have not looked yet to see if the bellows will be in a location to for additional clearance issues.
Right is ours.
Pic of new yokes.
And if you can see on drawing, marked out the centers for the 3 bolt and both 4 bolt.
Should be fine is I used the yokes on deiveahaft, it is close.
But would have to drill and tap holes but instead on bolting on, would use lock tie and studs for the flanges
