My wife really needs to stop asking me to take her to Hobby Lobby, LOL. Or is it I really need to stop asking her if she wants to go? Anyways, I got these two today. The '67 Chevelle chassis fits the '55 Chevy so that's what that one is for. I chose the GTX over another 1970 1/2 Z28 because I don't have one yet, but have two of the Z28's, one built, one not.
