Looks like the majority are in agreement, the green one has a better look to it, but the purple one looks like most of these early body on S10 frames, just not right.
I "get" why someone would do this, logically it seems to make sense. You put a newer frame and running gear under an early car and reap the benefits of later suspension, brakes, etc. But sometimes there is a lot more to building a car, like style. Regardless if a person is building a rat or a high point show car, there is still style to consider. Otherwise, you could plop a big wooden box on any frame and call it done.
