BCUDA IS STARTING TO TICK ME OFF

Went through a similar issue with my Dart. Had about 200 miles on the car since restoration. Lots of "weird" issues getting worked out and after I finally felt like I had reached "Mecca", I got ready to take it out for a nice little cruise. Started to back out of the garage and when I pushed the clutch in, out of nowhere came this rattle sound. wtf. Only happened when pushing in the clutch. Needless to say I didn't go anywhere and like you, I had to put it back on jack stands and see if I could figure out what was going on. Pulled the inspection cover off and 2 small ball bearings from my Centerforce pressure plate fell out. They're what the fingers pivot on. I was pee-ode big time. Had to pull everything back down and I too had TTI's and it was a PITA to have to unhook the exhaust to get the tranny out and pull the clutch all back apart. Probably not what's going on with you as you can "feel" something hitting, but I can appreciate your frustration. Also those ball bearing did make a bit of a knocking sound too.

Good luck to you.
