There are a lot of drag race steering columns available. I looked at a few when I was building my Duster but eventually I decided to keep the stock column since I needed an ignition key and turn signals. It was easier to keep the stock column that it would've been to fabricate turn signals and a new wiring harness for the ignition switch. If it is a dedicated drag car then you don't need a column unless the rules require it. I've seen a number of cars that have the steering shaft supported in a rod bearing.
