did yours come drop-in for RWD KA? the original set made was given to AMS, and they were made from FWD blanks for altima, so one had the distributor gear drive on it for some strange reason (who the fuck buys altima cams?). i'm assuming the next batches given to enjuku and other stores were revised. AMS must still be carrying the fwd versions, they still have the notice up that they'll cut it off for you (which in itself is sketchy).
