The serpentine system is a GM product and is an option with GM proformance crate engines. Like any business GM makes mistakes.
I took the shrink-wrap hardware pack back to the dealer that I bought the engine thru along with the air cond. bracket. I showed him how the stud for the bracket was at least 1/2 inch too short. He called GM and discovered that there are two packs one for air and one without air. They sent me the one for without air. All the hardware in both packs are identical except for this one particular stud which is 6" for the bracket with air and 5.5" for the bracket without air.
They are overnighting the stud and perhaps tomorrow we can "get er done."
Thnks for the help guys...
If this doesn't work I'll yell back.
