A833 rattles with new clutch and throw out

I have a 73 duster 340 with a 4spd. when stopped there is a rattle from the clutch area. Doesn't matter if clutch is in or out or if trans is in gear or not. When coming to a stop, it rattles quite loud as input shaft slows down but never completely stops rattling. Rattle can be heard in between gear shifts as well. Has also developed a slight vibration at 2000 rpms I just replaced the clutch and release bearing last week and it seemed fine. Clutch is adjusted with 1" play. I have only driven the car maybe 50 miles when this started happening. This is my first Mopar with a manual trans so I'm not as savoy as I would like to be. If someone can point me in the right direction it would be greatly appreciated.
Thank you in advance.
