you will need the specific tool kit.
both for removing the old bearing, and installing the new one.
i think that flat6 is coming out with a new tool that removes and install the bearing in a better way
Faultless IMS Tool
but the old kit will do the job as well.
try to look for a used one on one of the forums (911 forums as rennlist.com is good as well).
i have a tool kit that i lend to people here on the forum, but shipping it back and forth to malta will not make an economical sense to you.
