I’m not sure what the purpose is for the frame work in the cargo area.

“1948 Willys Jeep CJ2a runs great, many new parts including: gas tank, sending unit, gas gauge, ignition switch, headlight switch, hi/lo beam switch, steering wheel, spark plugs, fuel pump, and fuel lines. Also replaced exhaust manifold (cracked) and gaskets. Included but not installed new shift boots, master cylinder, plus more new parts. Engine, transmission, and transfer case previously rebuilt and work as they should. Carb rebuilt a few months ago. Recent oil/filter change. 4 of the 5 tires are very old, but all hold air.”
