Go to your local hardware store or DIY center. Ask them for a furnace
thermocouple. Get the longest they have. It is a long copper tube, about
1/8" diameter, with a bulb on one end and nut on the other. The longest
is usually 36". Cut a piece of the of the 1/8" tubing about 1/2-3/4"
longer than the inside diameter of the muffler where the big nut screws
in. Not put mating angles on the ends of the copper so the to ends can
over lap, but be the same diameter as the original tube. Use a file, or
a grinder, or a dremel tool to make the angles. Keep fitting until they
just fit snug into the hole. Now, put the nuts back into the heater
boxes, and tighten them down. You won't be able to tighten completely
until the muffler is back on the engine and then check them again after
the engine has been warmed up completely a couple times.
