Even before the recent string of e-mails, I knew my rear heater was leaking.  I ordered the o-ring, optimistically hoping that it wouldn't need anything else.  Actually, I was determined to pull out the whole thing, at least for now, if there was more wrong.  Well, there was a lot of corrosion in the core so I pulled it.  I don't want to take the hoses out back to the T because I might want to re-install it.  (Re: when I have some disposable cash.  Ha!)  I was going to plug the two heater hoses with 7/16 bolts about 2 inches long and clamp it tight.  Any problem with that?
