we have done 5 of them...4 are complete and the 5th I am doing for myself.
I have yet to see one of our trucks look like Frankenstein. It does take some planning and yes the track is wider but I have it down now where I use a jig that will show where the Rad support needs to be....everything lines off of it when putting inner and outer fenders, hood etc back on and can weld a clip on in one evening.
Like you said you can buy a whole car for a little bit of nothing and then sell off what you dont need.
The one I am doing now I piad $150 for a 78 Trans Am no motor.
I have a good rear, pedals, clip and tilt colum. I sold the tranny for $60 and the rest of the car for $150 to a guy whho is making a street stock dirt car.
here is the one I am working on now
I sold the tranny for $60
