I just spliced the Yaris shafts into the Pantera column making couplings and using 10-32 "aircraft grade" hex bolts and locking nuts.
The DD shaft sleeve has so much engagement that being precise on the length of the engagement of the male and female is almost insignificant.
On mine the part on the input shaft with the splines just got removed to leave as short as possible a stub for the coupling for the Pantera input shaft.
As you work on mating the two together, and realize that the new assembly needs to be as compact as possible to fit it in, you will see that is where you need to cut the Yaris on the input side.
The necessity of retaining the Pantera ignition switch and directional signal mounting will be the determining factors.
The output on the Yaris will also be as short as you can make it and also retain enough shaft to mount the universal joint.
