Just gave "Leadfoot Racing" a blast...not only on this one, but several other instances I have had issue with over past few weeks...
told them to get the lead out...hahaha
"1/2" 20 STRAIGHT THREAD G1/4 is recommended as the fitting for the auto trans cooling lines in several of your radiators....perhaps it would be a good business idea for you to actually stock these fittings in house so your clients don't have to search for weeks to find a fitting....even calling your supposed help line resulted in a "we dont know" response....Graingers stock these as standard hydraulic hose fittings...

Maybe get the lead out and get some knowledgeable customer service reps...."
