Yeah, if you want the lower parts out to remove the bolt and stuff you'll need to yank the hammer spring/strut (seems like a beefy spring BTW). Then the pivot screw for the hammer that goes through the receiver sides should come out easy. I couldn't find a decent hammer spring tool while at my bud's so didn't go that route- just dropped the finger lever.
Maybe with the busted cocking bar it came out easier. I dunno. I think I could insert a replacement full length part and the lever and fenagle them together before full positional placement. Heck they might go in as an assembly to start with, the busted one does (but then it's significanlty shorter).
I've been inside worse disasters (been sliced on some oldie but goodies doing repairs too).
This I think no big deal, if we can get an OAL of a good part.
Don't want anybody to break theirs trying to get me a dim though
