66 Valiant Vert RUSTORATION

I think you will find more differences as you study the two cars. On the 65 Dart, not only are the wheel tubs different on top, but the brackets where the trunk hinges mount are also different. Plus, you've got the structure where the convertible frame mounts on either side of the back seat, the convertible top well and that shelf where the pump sets behind the back seat.

You'll need to graft a big chunk of the back of the convertible onto your 4 door chassis, from the back of the door jambs to the rear wheel wells and across the front of the trunk. I'm not sure where you stop but maybe it includes the entire rear quarters back all the way to the rear of the trunk.

I think you're saying the 4-door is a 65. I don't know what additional problems that will cause. I think Darts were the same from the doors back between 65 and 66 except for the tail lights. I don't know if the same is true for Valiants.

Your 66 front clip should bolt to the 65 no problem.

What are the rules regarding VIN number. Ideally you'd want the convertible VIN when finished, but I don't know if that's allowed. But how would they know if you moved the VIN? Did you get a title with the 4-door?
