833 clutch rattle 66 Dodge Dart

Hi all, last summer I installed a Brewers 10" clutch and EVERYTHING involved brand new. I have had a slight rattle when clutch pedal is out. Today, the noise got quite loud, like holding a stick against a fan blade. Noise increases w/rpms, goes away when I push clutch pedal in 1/2" to !''. Everything is working fine, w/exception of this noise. I had nothing but problems w/this install, and now this... Anyone have any idea's? Thanks
