What's all involved? Is it an easy swap? 67 Coronet bolted to the floor style to newer suspended. Thanks.

The "suspended" style is still bolted to the floor. The standard one that your car was equipped with is similar in design to what was also used in the trucks for many years. It was bolted at the bottom of the pedal. The suspended style has a 2 bolt bracket that attaches to the sloped section of the firewall. You may need to drill a hole for the throttle cable to pass through. You will obviously need the newer style cable as well. NOT a hard swap. A friend did this to his kids 64 Valiant.
