That is exactly the cart that I have and I too inverted the top shelf after I saw it done on the other site, may have been yours. Did you remove the spring legs? I left mine on and attached four PVC pipe end caps upside down to the table top to keep the pit from moving, also copied from other site.
Wow, the memories come back....
I used small squares of shelf lining under the spring feet and a couple pieces of wood 1x2x16in or something there about, and placed/wedged them under the far left side of the pellet hopper, to stabilize the DC from rocking.
And yes, that was me that inverted the upper shelf on the other site, as well as adding a 45d copper elbow to the grease drain and added a wire extension to the grease bucket to hold it to the lip on the drain.. (Had to extend the drain to clear the edge of the shelf for the grease bucket)
(where the pictures went) - When photobucket went belly up and stopped allowing '3rd party views', I went and cleared my photos out of 'photobucket' and deleted my account. Then, shortly after, the 'other site' went south... That was a very interesting and informative thread on the DC and the different solutions many of us found..
