I have replaced a rear core plug on an RP without cutting the bulkhead or removing the engine. A rusted core plug can usually be removed fairly easily with a suitably bent poking tool, and then the seating needs cleaning as best you can (your home made poking tool may be suitable). Smear a bit of sealant onto the recess and fit the new core plug, then push a small hammer head or other suitable lump of metal between the centre of the plug and the bulkhead so that the bulkhead bulges slightly. The use a hammer carefully to strike the centre of the bulge inside the car. This will seat the core plug in the usual way.
