about the '62 Mopar kits, there are several companies who re-release vintage kits in an attempt to sell nostalgia, these kits are just that nostalgia and people who buy such kits, in a way try to relive the moment building a kit they had a a kid, happy non worrying times!
I'm sure if the tooling is usable, plastic will flow through the old gates, to form something which is bigger then it really is.
