Pics to bring back warm fuzzy memories to those of you who have battled this before:

Socket and hammer for re-installation is what I use IF I'm not off-angle. I had to use a hex-shanked chisel in a 13mm deep impact socket mounted on the end of a 12" impact extension. The only thing missing was the sound of banjos.

LF and RF: ~45* angle at best due to proximity of crossmember.

LR and RR: similar angles with added bonus on the LR - after starter was removed, turned out dipstick tube is dead centered over LR freeze plug. Had to remove that which snakes between head and exhaust manifold. It's a sort of press fit into the block (arrow pointing to boss in block - tube is just hanging out of the way for the moment). Getting that out without destroying it was fun. The approach angle in the pic is nowhere near as severe as the middles. Now you can appreciate what I'm working with here.

Middle on both sides required motor mount removal one at a time while lifting the other side with a threaded tripod (car's on a side post hoist - I doubt I could have done this on a drive on hoist).

I finally punched, chiseled, and muscled out what's left of them. I'd prefer not to use those rubber expandable freeze plugs, but I might have to except for the LR as there is not enough room for the dipstick tube to go back in.

What a turd. The price of allowing electrolysis to occur in a coolant system...
