Show your slant 6 a body!

1971 Dart that I bought for my daughter. We are building it together and it will be her first car when she turns 16. Going by the fender tag and vin, this was originally a 318/904 car. However, at some point in it's life, that was pulled and replaced with a 225/3 speed setup. I'd like to put it back the way it came eventually but for now she's still a slant.
