Suspension holding the weight is easy. Once the junk you want to remove is gone. The brakes with the correct bore master cylinder, piece of cake. Weight? No issue. I've seen them below 3200 with stock appearing interior, power windows, ect. Again remove junk you dont need. Air bags extra stereo, A/C, power steering, etc. The windows. Now there's an issue. Making them work without the BCM can be done . But it's not cheap. The earlier models window are a little easier.
