You can unhook the lines at the master and at the slave cylinder. If you pull the old line out as you put the new one in it is very easy to follow the same path. The space you're putting the braided line in is quite a tight fit but there is no way you need to pull the body off. Once you have everything connected you can bleed the system as described in the manual. I replaced mine and haven't had any shifting problems since. Lee VIn #1699
