New Drive Shafts Take Shape

With the exception of an 1140 flange and a shaft with slip yoke and 1140 flange  to make my new drive shafts.
Take a look at No 3 pic and you will see the ST1100 swing arm drive shaft and the remains of a CX500 drive shaft. Both UJ are the same so they can be swapped around.
So lets call the end of UJ end of the swing arm shaft A and the actual drive shaft B so AB makes up the swing arm drive shaft.
Lets call the two halves of the CX shaft C and D or CD with the bored out half D, now the tricky bit.
If we seperate all the UJ halves and swap B and D we now have AD, the bored out half married to the splined engine side, so now thw engine output will drive a meter long shaft and slip yoke/flange to the reversing G/Box.
Now marry B with C or BC,weld  flange on C , now there is a 1140 flange married to the swing arm shaft which will bolt up to the reversing G/Box, got it?
