Thanks for all the replies. Since there is plenty of room around this candohm, I may try and pry it open, gut it and leave the original three tabs and insulation to mount the new resistors to. This way no chance of the original candohm interfering with the new resistors, but will give me great mounting points.
At least I understood the schematic and wiring on this candohm and how to replace it with these two new resistors. Baby steps!!!
Each time I encounter a new part to replace that I have not done before, I learn.
