if I am wrong on any descriptions please let me know and do your research on the parts. I'm no expert on these cars or the 215 engines. NOS 61-63 differential, I don't believe it has ever been run. 13737 and a 3 cast in it. $30 plus shipping. NOS 61-63 motor mounts for 215. $40 shipped. NOS Harmonic Balancer for a '61 215 $40 plus shipping. NOS Harmonic Balacer for a '62-,63 215 $40 plus shipping NOS Lower Ball Joint for a '61-'63 $35 shipped. I opened the container to make sure the ball joint was not rusted. Again, verify that these parts fit your application, I tried to figure out each part but I could be wrong. Thanks, Brian
