The only '70 car (of the 4 above) that may have its original hood & springs is the red HEMI car; a MOPARTS member use to own it, but I believe he sold the car. I have a "Made in CANADA" stamped (over the counter) hood & unpainted springs.
The VON of the black HEMI car & my 383 car are similar. The black HEMI car no longer exists.

My single 4bbl car and at least one of the '71 cars also has factory A/C!

All (4) 1970 cars have "rallye gauges" & 3-spd wipers. There was no "auto pilot" & hood restriction that I'm aware of.
The 340 car and my car are both SPD 702. 340 car was in Florida & I heard it went north to CANADA.

There was a restriction N94 - NOT/AVAILABLE on SE or with (A63) M31 due to the moulding on the rear of the hood. One of the '71s has M31, it's on the hood; the pics I've seen look legit, car was in need of restoration.
