You can find these at any napa location. Ok now I left the small part on to fill up the tiny areas first on both mounts. then cut down the a bigger size for the not so small parts.
For the larger sized area I took the whole cap off and squirted it in direct so i would not get any air holes.
Then used an old screw driver to smooth it over push any air out. once that was done I left them alone to dry 30 min later they will start to dry up on the out side it takes longer to cure the inside the most important piece of all.
