Looking for a few opinions on replacing a rear freeze plug in my 1968 Camaro with a 350 engine and TH350. Is it easier to remove transmission or remove motor mounts and jack motor up? Can I even get to rear plugs by just removing transmission? Not exactly sure which freeze plug it is, but almost posotive it is on back of motor. Water dripping down between bellhousing and flywheel. Planning on using a rubber expansion plug, which I have used before with no problems. Main question I have is, how am I going to get the old one out without removing the motor?? Car is a convertible so I have the "X" brace under rear of trans. Also, this will be done on my back with front of car jacked up. Thanks in advance for any replies.
