New Flow Kooler 1700 WP, but fan hitting radiator

what clutch is on the fan? i'm running the short hayden one on our dart.. hard to get my old fingers in to get the bolts started but it fits... :) https://www.haydenauto.com/en/products/fan-clutches/fan-clutch-types/low-profile-fan-clutch

i'm also running the flowkooler 1700 with no issues.. 18"fan too..

that alumn pulley is quite a bit thicker them my steel one too i'll bet...
