320i 3-row radiator

My newlyontheroadafteryearsofsittingup '77 320i is running warm with 
the present radiator.  (Hey! that might explain the cracked head I had 
when I bought the car.)  I replaced the water pump with a 2002 unit and 
matching pulley (larger pulley=underdrive) and removed the plastic 
*&#$@ fan.  The electric (boogie woogie) fan is working properly.
    The engine timing is correct, and there is 50% antifreeze mix in 
the system.  Thermostat is new and a 71 C unit, which means it holds 
off the hot running for, oh, 5 more miles each trip.  Every day over 90 
degrees F means I'm driving my necktied self home with the heater on.
Of course, the heater valve is broken anyway...

SO,
    I got a '77 320i radiator redone with a 3-row core for $160 here 
locally.  It is NOT an aluminum core a la '79-'83 320's, but an early 
brass unit.  If your 320i is overheating and you can't fathom paying 
$150-$200 for a new stock radiator, this is a viable alternative.  
Given I have a soon-to-be working AC system on the car, I need all the 
capacity I can muster.  
    The '02 pump gives you >1/2" more space too. 
    I have a 3-row 2002 radiator, too.  It is virtually new, and worked 
great on my 9.5:1 Webered/Stahl'd '68.  GoshImissthatcar.  Got to find 
a car now to use the rad! :)
