URGENT! need quick help-broke chit on the truck tonight

[67cst]

hey guys, tonight sucked, i was with a buddy heading to another buddys bday dinner, we were sitting at red lights and it went green, i punched it pretty good but nothing too intense, got half way though the intersection, heard 2 loud bangs, looked back and my driveshaft was on the highway, jumped out and grabbed it and though oh big deal a universal went, so i threw it in 4x4 and me and the guy i was with took it to his shop, i put some new universals in and went underneath and noticed my pack of overload leafs were gone and my regular leafs were screwed, the axel was all cock eyed, i broke my bottom to leafs right in half where that pin lines up with the hole, i went back on the highway after i knew i was missing leafs and couldnt find them, man im pissed off though. what i want to know is are the 2wd leafs the same as 4wd. there are a couple 2wds at the wreckers with leafs, one even has the overload pack of leafs and ill go get them tomorrow if i know they will bolt up, right now the truck is still at my buddies shop waiting for a new leaf...enough yapping though, if someone knows if the leafs are the same let me know pls...here is a pic of whats left of the front and rear universals from the rear driveshaft
