Much easier to tighten screw when installing then trying to drive steel bung in. I cut off heater portion. Did I say I was working at Chrysler then and they helped with parts. Regards lennyrebel

If the two on the back of the engine are about level with the manifold then those are not leaking. What I found tonight was my puddy job did not take. Fluid is still pushing out around the two rear freeze plugs on the side of the block. I pulled the puddy off of both sides and resealed them. The leak has slowed tremendously. There is still a slight leak. What is your recommendation about radiator stop leak? Do you think if I dumped a jug in the radiator that this may slow or stop the remainder? The leak is a drip from the freeze plug about once every ten seconds. I am going to pull the plugs and replace them once I come back from Thailand but is there anything else that I maybe able to do so it is not leaking as much? I do appreciate the help with this.
