Motor drops out from below on the vans. You can pull it out the front if needed (that's what I'd do since I don't want that heavy tank balancing precariously on really high jack stands with me under it). You can also remove your seats and pull it through the dog house opening. Don't forget to support the tranny so it's not dangling by the only mount...
I still think you don't have a serious problem. It started ticking, then stalled, and now it's supposedly froze. I'd have thought it'd have made a LOT more noise before giving up the ghost than you described.
Heck, a friend of mine had an old Scamp with a /6 in it, blew a hole through the side of the block, down through the pan, and part of the valve cover disappeared. Now THAT was a BANG! :B
Best part? He still drove for the rest of the summer! He simply poured free drain oil over the top of the open engine, and drove it until it over-heated, let it cool down enough to start up again, and continue on!
Not the best thing for the environment, but that darned car kept working, even broken that badly!
