blower alignment tool??

[thomasinnv]

my DD service manual says to use an alignment tool when re-installing the blower to the engine block, i assume for proper alignment of the drive shaft. is this tool a must have or can the job be done without it? could the same thing be accomplished just by using the drive shaft?

Clifford, had time to get to the P.O. yet? let me know what i owe ya.
