Rad/Condensor/E Fan & Shroud Distance OK?

I am currently installing a Classic Auto Air a/c system and electric fans in my '65 El Camino with a 350 and TH350 combo. It has a brand new 3 core radiator repro to OEM specs.

The a/c condensor:

The condensor has a gap between it and the radiator of about 1/2". There is no way to get around this as the core support opening doesn't allow for the condensor to butt up against the radiator. Is this okay? The condensor covers about 90% of the radiator surface so I believe I have good coverage there. But I worry that the 1/2" gap may cause the air not to flow good thru it and then thru the radiator. Should I build some kind of flaps to run along the sides to cover this gap? Or is it okay and I shouldn't worry about it?

The electric fans:

I've purchased a Spal dual 11" electric fans that cover all but about 1/4" along the bottom of the radiator. I think this should be good enough, better than most fans I see installed. But in order to get it mounted to the stock radiator flange (the '65 rads have double flanges, one side to mount to the core support and the other side to mount the stock shourd) it leaves a 1/4" gap along the top and bottom between the fan shroud and the radiator core. Also when mounted, the fans blades are about 1" from the rad core.

First, is the 1" distance between the fans and the core fine? The fans are in a shroud (its the Spal 30102052 fans). Next, does the 1/4" gap along the top and bottom need to be covered up? I was hoping I wouldn't need to add too much fab work and not have a clean looking set-up. But, of course I want it to work the best cause of the hellish AZ heat and the a/c running almost all the time.

Any suggestions are welcome and thanks in advance for your help.
