1970 Duster project in Sweden

So I have spent time fixing things and crossing things off the to do list. Been driving it a few times too. It feels great.
Now I need to look at the cooling system. I have no shroud, I need one and possible a new radiator. We shall see. When I cruise I'm around 176*, but it creeps up when I idle or drive slow. I was expecting that with no shroud. So I'm either gonna see if I can fabricate one or get a aftermarket one like this. It's for a 22" radiator. Do any of you know what size fan I can have with one of those?
