You'll find the cross bar handy to hang other things on.
I have an under-dash instrument panel, turn signal/horn button panel and small choke bracket on mine.
As well as the column hanger and some switches that are hung behind the cross bar.
Nice place for a couple of ground terminals as well - fiberglass especially and it doesn't hurt for the steel car.

Next things to hang from it will be a radio box similar to the one Dan Fink builds and a small open face glove box big enough for glasses, gloves and a few other small things.
