1971 Dodge Demon

Is that the original color? Does the motor include any gasket or ring set? What color is the strip set? Just to be clear there is no wiring harness for the gages? And the brakes you said you installed new lines. Did you change over from drums to disc? I would think the 71 would have drum brakes. 38 grand and atleast another 15 grand . That's about 55 grand. Thats more than the excellent condition car in your list which I'm guessing is an fully functioning working car and all parts are there along with a running motor.
I have not found any other color on the car, but can not absolutely confirm its the original color. Stripe kit is black, no wiring for the car, except the headlight wiring is in. When I purchased, disc up front, drum in the rear and all new brake lines on all 4 corners and up to the engine compartment
The motor will be rebuilt as it is torn apart now

Not sure where you are getting $38k + another $15k to finish it?
