Where does the speedo cable pass through the firewall on a 72 Dart?

All the docs I have are not really specific, and just say it goes through the firewall. I can't seem to find any hole for it.

The cable comes off the back of the cluster and goes straight back through the bracketry under the dash that the pedal set hangs off of. It typically exits through a rubber grommet just above and to the driver's side of the master cylinder (varies a little by generation...). Then goes down the firewall, under the driver's side floor pan (look for some metal 'tabs' it clips into, then back to the speedo gear enclosure on the driver's side of the tranny.

In theory I have working speedo now, however looks like I got the wrong cable. I appear to have upper and lower with a canister in the middle, so my cable is a bit long at the moment. Appears as tho the canister and lower cable are already hooked up. Upper was all that was missing. Won't know if it is working for sure till I get the distributer and everything back in, which the new vacuum advance pod isn't here till monday.

The reason I didn't see that hole before.. The old speedo cable was still there, but it was in fact cut almost immediately behind the wall and it was just the outer tube. So hole looked used. She sure has lots of "character". :-)

Do you have a picture of this?

This sounds like an NOS 1975-1976 A-body speedo with the EGR timer still attached in the middle.
