I replaced my mounts when I did my oil cooler lines 2 years ago, if yours are new, keep them, but do remove the drivers side shock and mount while removing/installing the cooler lines, it makes it way easier. Be prepared to become unhappy when taking those out/especially putting in the new ones. It took me an hour of fighting with them to get the new ones in. To get the old ones out I just cut them in a few places with a dremel.
