Antenna cable routing on a 1970 Challenger?

[750-h2]

From the factory was the antenna cable positioned above or below the heater box?  I think it would be cleaner looking to mount it on top but the cable appears to be a little too short? Thanks.

Should clip on the back of the glove box, but most of the replacement cables are too short....
