It looks pretty good!

From what I can the springs don't look like the original ones. Mine are rounded at the end of each leaf instead of square like yours. Best way would be to buy new springs or at least used from a salvage yard or local member to you.

The fuel tank looks like a aftermarket blazer tank. I have the same one. I can't be sure of the the plug is for, but it looks like the high amperage connectors used for electric forklifts. Probably something someone put in for trailering, or powering a winch etc... It also looks like the side vent hose on the tank is blocked off.
