Mine was a 1971 VH6-H-29 Charger 770 automatic with the "Fireball" 318 2bbl.
It does not exist now.
Apart from the chassis rail i also had to replace the inner and outer sills, all bodywork from 10 inches up, and the top few inches of each front wing (fender).
No spares available. I made all the sheet metal bits myself. The tops of the wings were too tricky for me though so they were "repaired" with chicken wire and fiberglass. Finished off with a thick later of body filler!
The boot lid I made from scratch. It was not as flat as I had hoped to make it.
Then I set fire to the rear seat when welding under the car.
I was lucky the rear window smashed from the heat because the flames went out that way and saved the rest of the car. I had the fire out myself (with Dads help) before the fire brigade turned up.
That was fast work because I lived in a third storey flat and I only had one bucket to fill with water. It took four buckets of water to put the fire out but only bacuse my Dad managed to remove the back seat and let it burn away from the car.
So after that I had to make a full interior myself.
Grey bathroom carpet (rubber on the back) for the floor and two shades of grey cloth material on home made door cards that matched the race bucket seats I installed.
I also made an ally dash panel to fit all the guages in and for the top of the center console because the heat had damaged them as well.
I never replaced the rear seat. Just fitted two big hi-fi loudspeakers in there instead.
Well I was very young....
