Need help pulling my 273

You definitely want to separate the engine from the tranny at some point. Look what I found on mine! I could have replaced the side freeze plugs, only to be doing it all over again to replace the rears. The pics you see are the rears, original since 1964!

Exactly. At this point it's called a complete repair. While it's out you'll want to do them all so you won't have to pull it again to do the backs.

nothingbutdarts is right: you've got to hammer 'em out and hammer 'em in, so you'll want to pull it enough to swing a hammer.
