Upon further investigation, I have determined that the dial cord routing I found on the chassis is correct. If it still slips a bit, you just have to keep tightening the connection to the spring until it stops. I have posted a hand drawing of the routing for the benefit of anyone who obtains an L-640 (and most likely, also an L-641) where the dial cord is broken or missing.

I am very much in need of a dial stringing diagram for a General Electric model L-640 3-band table radio from 1941. For some reason, it never made it into the schematic pages here from the General Electric Radio Service Notes 1939-1942, nor has it made it into the Riders. Model L-641 uses the same variable condensor drum assembly, GE radio part number RD-426, but no dial stringing diagram appears for that model either.
Is it possible that the diagram does appear in the GE Radio Service Notes, but on a page that is not contiguous with the schematics for the L-640 and L-641, so it was missed? If anyone has a copy of those service notes, I'd appreciate it if they could check and let me know.
