Charlie, the chassis is the same as the Revell '59 Impala, so the spare tire well was removed and filled as the '60 stored the spare flat on the floor. The rockers hang down below the body, so I cut them off and thinned them down and re-attached. The exhaust exits behind the rear wheels so pipes were shortened and bent. The front spindles were cut off and moved forward so the front wheels didn't have the "knee back" look to them. Revell dropped the ball on this kit as far as I'm concerned.
