Steering Column Hold Down

Can someone tell me about the steering column mount, please?

I see pictures on the web of a bracket holding the column attaching to something somewhere on the firewall, maybe? Now, I see that Summit Racing has some clamps, like the ones listed here:

But there are 10 pages of them....I can just see me returning parts every day for the next year. Will any of these fit? I'm sure that someone has a better idea. Please let me know what you use.
