Looking at an E body 70 challenger

I've been looking for a 70 JH donor car just like this

For what purpose? This car is too nice just as it is to 'donate' anything towards another car.

The N code is the HP and will be street Hemi orange.

Not all N code 1970 Challengers were HP and not all were orange. See the page at https://www.hamtramck-historical.com/images/TSBs/1970/D70-25-1 page5.jpg
