Looking at a 71' Demon

they sell hoods here: http://www.usbody.com/

your problem will be getting quarters welded in. most body shops will not touch that kind of work... if you cannot do it, find a friend that can, or you will have to get very lucky to find a place that will. they cost $$$$ too.

i would only offer $1500 max. it's gonna cost you 3g to get it on the road probably. engine + trans. you may be able to find a cheap 318 or 360 + trans. but still, when they are dismantled it's a big project.
