Removing Distributor

[ModelAMitch]

Hi guys, I’m trying to remove my distributor.. this may be a newbie question, but the screw holding it in place is wedged between my exhaust manifold. I can’t see a way other then needle nose vice grips and crossing my fingers, likely ruining the nut to loosen it off. Do I need to remove the manifold??? I can’t get a wrench in there. I could with the condenser out, but I can’t remove that either because of the manifold. There has to be an easier way. Thank you all
