Thats strange. I have two flexy pipes to each side, one from the chassis mounted hard pipe to the beam mounted hard pipe and one from the beam mounted pipe to the caliper.
The goodridge kit only contains the new pipe for the connection to the caliper.
Mine is the coupe too but I'm not sure which calipers, I think they are Lucas. Possibly the rear pipes are different on the Coupe for some reason.

This pic shows the flexy from the chassis hard pipe to the beam hard pipe.

This pic shows the caliper flexy connection.
Sorry the photos are not clear butthese were taken a couple of days a go for my records.
Maybe someone else can clarify things for you.
