These authentic (ammo box) heatsinks were sourced from the original location that the original crew did back in 1989 ( This Heatsink is ONLY featured in Back to the Future II & III ). You will need to source your own ammo box and L brackets for mounting.
The "Back To The Future Delorean Time Machine Ammo Box Heatsink" would be an ideal fit for anyone building a time-traveling vehicle or a DeLorean model in their workshop.
