yep...definently wrong. the cock vane must be centered to pass through the 2 prongs. the cock vane would be your white one. that way its easy to remember..white vane down. i cant tell if you have adjustable or glued in nocks though. if you do you can twist them and align them pretty easily. both times i had arrows done the shop didnt touch the nocks. i had to do it. but its not a big deal with adjustable nocks. just twist them.

also looks like you have a helical on them..gota watch for vane contact even if they are centered. is the rest old?? same style/diameter arrows?? if not you may need to adjust the gap of the prongs also to accomadate better. good luck..let use know if you need help theres alot of good guys here
