Got the oil block off broken bolt out with
@89Suburban technique, thank you!
Tried drilling with angle drill attachment but it's almost impossible to get in there at right angle due to tight squeeze and the only bit that fits was from ez-out and it couldn't drill the bolt at all.
Couldn't squeeze anything else in there so decided to go with angle grinder with flex shaft.
Had to cut a little piece to the side of the bolt, away from oil tube holes, but finally got the bolt out.
Put in some Red silicone, new bolts and everything back together.
Added some extra oil that leaked out and everything seems smooth, no leaks so far.
Decided that while i'm down there, go back to the front diff fill plug bolt and noticed after cleaning rust off of it that it's completely rounded
Will have to figure out how to get it out, but that's for another series of "how messed up is messed up".
Probably get myself a welder, weld a big nut on that rounded bolt and get it out.
