Cooling system issue....

[wwotr]

I have a 72 GMC, with a 350 put in by the P.O.
I was told it out of a 94 GMC Truck 1500.

When I lived up in Nor Cal, it would run at 190 Degrees,
all day in 90 degree weather.
Today was the 1st time I've taken it out in the Heat,
(since moving down here to So Cal, Palm Springs Area).
Left the House at 11 am, and it was 100 Degrees out.
Drove to the Gas Station (about 9 miles away), on City Streets doing 45-55 MPH, with the A/C Running.
Didn't even bother to look down at the Temp Gauge until after I got Gas.
It seemed a little hard to start after I filled up.
Looked at the Temp Gauge and it read about 210.
I started driving, and got about 1/4 of a mile and the Temp stayed around 205.
I took it straight home, as I knew if I got caught,
in any "Stop-n-Go" Traffic, it would overheat on me.
That got me to start looking under the Hood.

What I have is a Serpentine Belt System, with No Shroud and what looks to be a Cheap Brand "Flex Fan", mounted on a 2" Hub.
Now the Blades are about 2" from the radiator.

My 1st thought was to get a Shroud, Clutch Fan and Flush the Cooling System, and re-fill the Anti Freeze.

Money IS an issue, so if it WEREN'T, I'd be installing Dual Cooling Fans, and wouldn't need to post here.
I'm at the Tip of the Iceberg, looking through the Internet and researching this issue and what's available.
I was wondering if someone has made a shroud to fit our 67-72 Chevy/GMC's that has an electric Fan built into it already?

I was wondering if I'm headed in the right direction with the Shroud/Clutch Fan idea above, or if I should go straight to a electric cooling Fan?
I've seen some single Fans that clip onto your existing radiator ect.

This is a real Generalized question/Post.
I was just wondering what others did with the same problem as I have, and how you corrected it.
