Can't get a break

Everything is on the bench. The one I'm working on is from ebay . I cleaned it with electrical cleaner and then put some graphit on it and lubed the cable. This did help stopped the thumping but only goes to about 60. My other cluster is still in the car and diffinitly has issues , bent needle and just flip flops. It is a 67 with the screw in cable. I'll try one last time to get something working ,if it dosen't happen I'll send one of them in to get fixed.
