I ordered the molded dashpad from lmc and it came with silicone. I still haven't glued it down with it but I've put several on in the past and it holds well. Just make sure to clean the old pad off really clean. I used rubbing alcohol to make sure there was no oil residue left to keep the silicone from adhering. Also make sure any high spots that are loose on the old dash are removed so that the dashpad fits flush.
