Anyone know how to build an adjustable frame table

[atomicjoe23]

Anyone out there built there own adjustable frame table. . .or know where I can get the plans so that I can build one of my own as well. . .I've seen them on TV on Musclecar and Extreme 4x4 and on Rides in the Rad Rides by Troy shop. . .decided that this is the way to go when building my '67 Firebird 400 coupe.

Thanks in advance!!!
