The actually fit of these trucks are NOT the greatest. But you should get the tail gate to fit withing 1/4 inch on each side if you square the side walls.

Once you get the floor boards in, you should be pretty close to getting the tail gate to fit.

No better smell than that of fresh paint. I've been building and painting cars/trucks for 47 years. Not gonna stop now.
