flywheel/crank balance

B20 swap, was auto gone to 5 speed .The rear end of the crank on the b20 has no pin hole to line up with the pressure plate. [maybe only engines w/5 speeds came that way] I dont want to place it on wrong! ,…I thought about bring it to tdc on #1. looking over the flywheel for a clue. but thats still ify…anyone got info on this?
