weight reduction ideas.

Was pretty disappointed when my 75 dart hit the scales. Just wanted to see if there are any good diets for a 3500 lb A bodie. (without me)I started with my front bumper and got 38 lbs out of that thing. Next will be a hood and a spool in my 83/4. Maybe cut my doors apart, Please share your weight reduction ideas and how significant the weight loss was, cause I have a long way to go..... goal is 3200 lbs or less.
