Settng timing question.
 

Ive got a situation here.
My 92 accord used to be an automatic. to set time you sighted the timing marks through the plug in the side of the tranny and watched the marks on the flexplate. I changed it into a five speed. and on a fivespeed you set timing of the harmonic balancer , but my block doesn't have the sight on the front of the motor. What do I do?
