Thank you Charlie... I will mount the bed to be sure that I have the correct positioning for the mini-tubs. I too have a non-stock frame with 4 link, panhard, coilovers, and a Ford 9 inch rear end. When I mocked up the original truck bed, which was not in good shape, that center hole was just about right, but I am awaiting a new Mar-K bed and I was hoping that I could use the collective wisdom of this community to install the mini-tubs before actually constructing the bed. Based on your feedback, and Kevin's, I am concluding that it is wiser to build enough of the new bed such that I can drop that plumb bob down and be certain of dead center before I cut up a new Mar-K bedside. Thank you both for talking some common sense into me.
