Question main panel boxes

I have a 30 plus year old house. My panel doesn't have a ground bus. The grounding is accomplished by having all of the grounds twisted together at the box and then, (presumably) grounded to a grounding rod.
I found while working on another project that one of my circuits was ungrounded. The open to ground was between my first junction box and the panel.
I want to mount a ground bus to the panel, and then ground each circuit to that bus.
Is this a viable solution? And if so, are there any special considerations?

Is this a viable solution? Yes, If you should look in the electrical box on the face cover inside you should see a documentation about your box (make, model, so on), and it should show compatibale type of grounding bus bars to use with the type of panel you have, Also check the amps of the breaker box, we might need to determan the greounding is propperly hooked to each location the electrical code say's it should be hooked to, and for propper wire size's that are hooked to the ground rod, and the water line, if it is.
Good luck.

Thumbs up

Thanks Art,
I ended up mounting a grounding bus in the box and just hooking up a couple of ground leads to it. . .ones that weren't in the original group of twisted ground wires.
The box is properly grounded.
The circuit that was giving me the problem initially turned out to have two more recepticals on it. I found the open ground in the one closest to the remainder of the load.
The box is now fine, and the circuit is now fine. It's nice when a circuit is properly grounded. Thanks again.
