Well im putting the opti back in there, and There is that square side, and then two circlular ones. Do those have to go a certain way? In the hole I see 3 bolts, and then 1 lil dowel thing sticking out. Does that have to go inside of the square hole on the opti or what. How do I know?

Please help me out, gotta get this right before i put the car back together. Thanks guys.

 

Opti

 

This is what I did..

Since you now know where to put the pin into.....Here's a tip on trying to fit it on.
You might need someone assist you first off. I had a buddy shine a light down into the timing cover where the opti drive goes. The hole on the opti pin will line up with the cam dowel pin when you insert the opti. When you think you lined up the hole on the opti pin to the pin on the cam...push the opti in and you might need to have your buddy wiggle the crank pulley so it pops into place or whatever up the opti drive. Once it slides in, push the opti in gently and there you go....make sure it's lined up because it may appear in, but the cam bolts may not be lined up into the opti drive spinny thing, ha ha that was technical. Anyhow...just use patience....that's what I did...hope this helps.
