This is a replica that was very well done – modern drivetrain and suspension has been well-paired with a very true-to-form replica of the tube chassis, and the overall dimensions of the car are right. just looking at it, I can tell the body shell is taken from a mold pulled off an original car. Originally, these had a heavily tuned small-block Chevy and Muncie 4-speed, with NO driveshaft! The trandmission yoke was mated driectly to the differential yoke with one U-joint!
