I bought this kit last summer on eBay. It is an old tooling, but didn't give me too many issues.
DO NOT buy the newer 1972 kit (reissued in 2012 with an orange car on the box). I bought it, and the tooling has been reused so many times, parts of the body are distorted. They also removed all of the extra/custom parts from the kit.
Hope this helps! Good luck, and have fun!
