I have a ferret with a broken gearbox dipstick. I am trying to remove it, and boy is this thing stuck. Will not budge. Before I mangle it too bad, I am trying to figure out if this dipstick is threaded, and if so, RH or LH threads. Any ferret owners out there who could let me knkw. Also open to any useful tips. The transfer box dipstick is OK, and it pulls right out.
