Emergency brake 1957

I just bought 1957 CpeDV and the rear emergency brake cables are missing. How do the rear cables connect to mid swivel bar. A picture would be helpfull as I don''t have my service manual yet.  Thanks

Typically, on the older cars rear cables rear cables would be attached to a common part bar or cable, and a bar or bracket would center it under car to keep right cable away from driveshaft.

Thanks for The Help.
