Ball bearings falling out

65 dart just did a swap from 318 to 340. Manual transmission. Has a loud weird noise and the engine slowed down like the clutch was grabbing when i depress the clutch pedal. So I take out the trans to see whats up and i have 5-6 small ball bearings on the groundThe clutch absolutly grabbed as i can see the clutch mess on the flywheenl and pressure plate. I took apart the thow out bearing to see if they came from there and they are smaller than the thow our bearings ball bearings. The clutch i used in a no name brand from auto zone. i was trying to save a buck. It is a diaphram style 10.5 inch clutch. Does the pressure plate or clutch have ball bearings? I took the bearing retainer of the trans and there is no place for these small bearings to slip past the front bearing- Any thoughts on this one?
