Quick question fellas,

I bought a Yakima bike rack off my friend who's car was totaled for a steal of a deal price. The only thing is he had a civic, so I just purchased new Q clips online so that it would mount appropriately on my roof. The Q towers are universal so luckily all it took was 70$ to make it work as it should. Now, for our lancer (and evos i think) we needed the Q102 and Q83 clips - question is: which clips go in the front and which go in the back?

any help would be appreciated!
