Jesse,
I can help you out with a rear brake caliper, brake levers (stamped "Schwinn Approved"), and drop bars. PM me if you are interested.
CK******* equates to a C=March K=1974 build date. Check out this link. Schwinn Chrome loves to be brought back to life using Oxalic Acid (Wood Bleach in the hardware store) and bronze wool. Thanks for coming by C&V!
