They will only fit right one way, large end down. I see you have aftermarket springs but I have never seen any that will fit right in the lower pocket if they are up side down. To get them back in try taking your brake line bracket off at the controll arm (one bolt 13mm I think), then put a bottle jack in between the axle and bump stop bracket on the frame. Some times you can "tweek" the axle one side at a time and get them in w/o a compressor. If you can't get it DO NOT buy a cheap compressor! The one I use is an old snap-on it has a thredded rod with hooks on one end, and a "fork" that you slid on the top. To compress the springs enough they will be under EXTREME pressure and you have to put them in with the compressor still on the spring. You need one that works on the inside of the spring. It's not worth loosing a hand over.
