Installing my opti, where does the dowl pin go in ? Is it where the special shaped box is?

 

well doesnt matter now, i looked at shoeboxs site, and i had the cam about 4 o clock position so i figured to put one of the open deals over it and make sure the special grove was above it, i think that was right. But i put it on and one of the corners broke, so now im grabbing a new one from Dal!

 

That's correct. Not the ones that look like half of a cloverleaf.

I should have said half of a 4 leaf clover.
