Fan clearance

Just got a quick question I put a new aluminum radiator in my 65 Valiant.. which is a little thicker than the stock and not thinking yesterday when I installed it and it was fun trying to get it in there but I got it in and mounted... today on break I was looking at it I have about a quarter inch gap between the fan and radiator and as I was looking at it I noticed which I didn't think about it yesterday I got a one inch spacer on the fan will that quarter inch Gap be fine? Or should I pull the radiator out and take that spacer out?

If nothing ever moved 1/4 would be fine, but things do move.
I would SOOO be pulling that spacer, because an extra inch space is going to make WAY less difference than the fan hitting my new radiator.
