I’m hoping you post your progress on the forum, I’d love to see your work! In my research for the BTK Demon, I found a lot of information on the McCandless car, the restored car has coil over rear suspension and the original had leaf springs, depending on the version your trying to replicate. The video on you tube about this car is really interesting. It was a very dominant car in 72. Someone needs to cast or print a 72 Grille for this kit!
