Foot Well Table - Where can I find....

I've started my build,
finally. Almost done with the chasis. I'll have pics soon.
I'm currently looking ahead a bit and thinking about the foot well table. I want to use a double side pipe with threads on either side so one end can thread into the floor of the well and the other on the bottom of the table top. I've seen this method used in the forum so I know it's been done.
My question is where can I find the pipe and mounts?
Thanks,
Mike
