Sorry but you must remove the entire dash. The car was built around it, or so it would seem. Be very careful to reconnect the vacuum lines when you reassemble and draw a vacuum (suck on the lines)to make sure that each vacuum diaphragm is working and functional. It will save you a lot of work and time if one of these needs to be replaced along with the heatercore. These vacuum chambers control the doors that direct the air to the defrosters, cabin and floor. If any of these do not work or have a vacuum leak then your engine will have a vacuum leak. Your engine does not run well with a vacuum leak.
