[DeTomaso] Replacing stock cooling fans

[Jim Gray]

Doesn't Quella's setup use a Ron Davis radiator?  I remember the setup being a bit pricey that's why I went with the Fluidyne.  Now, if I could just get it to cool 8~)

If I had the money to do it all over again... I'd go with Quella's.  
It's all set up, ready to run, fans included and 90 degree elbows on  
the radiator so you don't have to monkey with any corners.
