New to A bodies

Greetings - I'm just found your site while looking for parts for a '74 Dart I just bought. I've owned several B body cars (69 & 70 Super Bees, 70 Coronet 500, 69 Road Runner and 73 Road Runner) but this is my first A.
Background on the car: 1974 Dart, apparently started life as a white hang ten car with a 318 2bbl. but sometime during its history someone placed a complete '71 demon cap on it and installed a 4bbl intake and carb.
I'm looking forward to finding out more on my car and get some much needed help with it, as well as making new friends.

Brad
