Anyone got any quick way to replace the heater core on a 75 monaco with A/C? Or am I hoping here??!!

Ghostbluesman put the service manuals here:

I haven't read the manual on it, but I'm guessing the most time consuming step (and for which I'm guessing there wouldn't be a shortcut) is to go through all the dozens of things that need to be disconnected so that you can remove the A/C box.

You're hoping.... You have to take out the black fiberglass box as a unit. Remove the upper metal dash panel and lower metal dash that contains the glovebox. Disconnect all the vacuum lines and label them as to where they go, disconnect the operating cables, then remove the heater hoses on the firewall. There are six nuts that must be removed on the firewall that attach the box to the firewall. On the inside of the car there is an upper bracket on the box that holds it up in the dash, remove the nut from the threaded stud. The foot air and distribution box also have to come out. Once the box is out, remove the upper cover and inside will be your leaking heater core. Take the time to redo the door seals and lube everything before putting the new heater core back in. I pressure checked my new heater core in a large bucket of water before I installed it and I am glad I did because it leaked at a soldered seem. Check the A/C evaporator as well. It goes back in easier. Good Luck with it!

No quick way then!!!! Oh well, worth a try. Many thanks for the pics. I have ordered the core just hope it's the correct one. That's the trouble with being in the U.K and never having a monaco aprt before to see what things look like!
