As an aside, I went to look at a 1:1 '74 Road Runner for sale about 20 years ago. This was back when old muscle cars might still be sitting on the street once in awhile. It was pretty original- worn, original-looking red paint, no stripes (just Road Runner emblems in the right places), standard bulge hood, black bench seat interior, a 318/ auto, and NO power steering. The VIN checked out- making it a genuine Road Runner.
One test drive convinced me not to buy it. It was in good shape and ran well, but that manual steering in a 4,000 lb. car was a real bear. I had a driver with manual brakes years before and that was much easier to live with. I guess I could have swapped power steering in, but at the time I didn't feel there was anything else special about the car so it wasn't worth the effort to me.
Nowadays, you don't see many old muscle cars, (especially Mopars) without stripes, with bench seats, or base engines (base in the RR was a 383 in '68, but just a few short years later, the base mill was actually the bread-and-butter 318).
I think I'm going to have to build a model of that car.
