I haven't been able to track down my Powerdyne installation manual for a BD-11a installed on my 1997 Chevy Silverado (5.7L Vortec). It would be greatly appreciated if anyone can point me to a copy. I had two bolts shear off holding the supercharge mounting bracket (and some pulleys) to the engine block. Guessing that bearing and/or belt are worn/broken and is causing a vibration, that over time, had caused the two bolts to shear off.

Thank you
