driveshaft liine up techniques

[Chenige]

Any hints on lining up a driveshaft with the motor?

20" mono with very little length to work with. The bendable portion of the tubing is about 3" from the stinger forward end to the motor collet.

I am making up new motor mounts and the motor will be as low as possible and I will be able to adjust the motor angle by bending the mount.
