1979 400 4 speed speedometer cable routing?

[oak]

Hello anyone have pics as to how the speedometer cable is to be routed and secured it had a bracket that mounted to bell hosing but it looks to have been fabricated. Thanks in advance

Most stock routing I've seen runs under the left subframe and attaches with a clip to the floorboards, still looking for a good closeup pic. Maybe had headers at one time?
