I started one over 40 years ago, but Life got in the way. It is still in the garage buried under a lot of crap.
It was a 1966 Town & Country wagon cut off into a pickup like an El Camino. Pretty much Gerald's Dream, without the fancy power plant. It needs major support underneath. I was going to drop it over a 4WD pickup Truck frame for strength, but I think it would look better at the stock height. The entire front end is clean with no rust or dents. The floor has a clean patch riveted in front of the driver seat, and now the entire floor is rust free. I have a console shifter from a '69 Charger and the original bucket seats. I also have the doors from a 2-door '66 Newport that I was going to try and incorporate into it. I moved the rear electric window up to where the C-posts used to be. I posted some 40 year old pictures on my profile page. It has been buried in the Garage ever since, clean and dry.
I also have a pretty much complete '66 Chrysler T&C that I kept for parts after I totaled it. I had replaced the front end, but never got it back on the road. The front end fenders and hood have no dents, just some surface rust and may be salvageable and possibly the tailgate and one or two of the doors. Most of the rest of the body is rusted beyond any kind of repair from sitting outside. The front sub-frame is still in excellent condition. I still have most of the black interior panels from both vehicles, and extra chrome trim from the Newport.
I am at the point now where I have to get rid of both cars. I would love to see someone complete the job, but it is probably way beyond what most of us are capable of doing. It is likely only good for parts now. If anyone is interested, give a holler.
