Chevy short box truck

I am not sure without checking title if an 84 or 85. It has a new gas tank in the box. Plastic shroud for original is still hanging below bed. New starter and brake lines. I drove it some around the farm. It was a farm truck and had been on the road. After the brake lines were done, pedal stopped almost on the floor, despite bleeding. It may be the booster or master. I didnt need it and just stopped driving it. It is not bad on rust. Has a corrugated steel cover screwed to box. Other quirk is the hood cable is hanging from grill with loop to pull. Truck could be road worthy or wood hauler or farm use. It has been sitting for a few years since started. No battery. 305 auto. One tire wont take air. It rolls. It has been moved to along road in field.
