As Taggart trips the first attacker with a stick at the lumber yard, all the other attackers can be seen already knocked down before he's even fought them yet. In the next shot they are all standing up again.
The Chevrolet 3100 seen on the highway prior to the semi ramming it is seen with a nonstock independent front suspension from a 1963-87 Chevrolet 1/2 ton light truck - the truck being rammed has the original i-beam (straight axle) front suspension with front leaf springs which was used by Chevrolet and GMC (the 1947-55 (first design series) had this straight axle front suspension which was last used in 1959 when GM redesigned the front suspension with control arms and torsion bars for the 1960-62 model year; coil springs were used with the 1963 - 2007 model years (its final application was the GMT800 where its current successor used a strut-like setup).

At one point when Jack is being chased by the coal truck, his own truck slides sideways and stops. Jack gets his truck back into gear and speeds off revealing on the left of the frame that the coal truck is being projected on a screen.
Near the end of the movie, Jack throws a flare towards one of the fake US Marshals who catches it just inches before it lands in a puddle of gasoline.
