Hi Kid!
That first one looks pretty good (don't know if it works, obviously). The engine looks a little scruffy -some of the plumbing looks crummy and the brace that runs from under the rear window to the the rear cross member should be triangulated rather than going to that vertical piece (I think they did that to get around the carbs). The rear suspension looks like it came off a Formula Atlantic car. Overall, it seems ok but it would be interesting to know its race history.
