Hi the previous owner had installed the stainless bed trim with double sided tape. I replaced my vinyl top on my 73 and I'm trying to install the bed trim back with the proper clips and screws. I'm about to go nuts trying to get the roof corners to fit properly. The pick above is the best I can get with out holding it down (no clip or screw) I put the roof clip and screw in and the gap gets bigger. What am I missing? Is there a trick to install these or a 3rd fastener I'm missing? As far as i can tell the corner pcs has not been bent out of shape.
