[DeTomaso] Fluidyne and Spal fan issue with Mounting fans

[clay willmott]

I removed my fluidyne/fan assembly that was recently installed prior to my purchase with the push in style pins.  They are the type that is pushed through the core.
 
I have had the radiator pressure checked and it tests fine.
I have now taken the radiator and fan set up to 2 shops where it sat for a week and then I was told they cant mount it or are afraid to weld on it.  I have called 4-5 other shops-no luck or they suggested the push in pins again.  The aftermarket plastic brackets that push through into the fans do not match up on the edges of the radiator and dont work.
 
 
Is there an easy way a DIY can get this done?  The fans and radiator are identical to the pic/catalog on the PIM.site if a visual would be helpful.
 
Any suggestions greatly appreciated.
 
Thanks
 
Clay
