I have a thing for vintage Holmes wreckers. So when I ran across this it ticked all of the boxes. It's a 1984 GMC K3500 with a Holmes 1200 wrecker and UTC-100 wheel lift. It has got a 454/SM465/NP205 combo.
It needs a little work like a passenger side fender, cab corners and rockers. The fuel system problem needs to be gone through; as after driving it a bit the fuel filter on the quadrajet plunged up.
