Need Help Finding A New Radiator

Hey all,  Now that things have settled down with the store, I'm going 
to restart getting the MIdget not to overheat.  Next is replacing the 
radiator,  I have a very specific core in mind.  

Can anyone call their favorite radiator shops to see if they can get a 
3 row staggered core that has 14 fins per inch, and is no wider than 1 
1/16"?  The tubes should be at least 3/8".

I've called about 10 places here in Austin, and come close a few times, 
but it's always missing one component.  

Thanks,

Mike
