How to remove this #$%$#* bolt

The head bolts between the springs can be a little tricky if the springs have been upgraded. 1/2" drive stuff usually won't fit, 3/8" drive sockets usually can squeak in there.

If not, try getting a thin wall socket. Most common application for that size is going to be a lug nut socket, they make thin wall sockets to fit into the rims. I usually try not to frequent Harbor Freight for tools, but I seem to recall them having a thin wall lug nut socket set that was pretty inexpensive...
