You can check with Emerson,
Emerson MotorSports - Emerson 427 - Bigger, stronger, faster, better. You heard this before, let us prove it!. His door hinges will work on the CR but the door will not open like a normal CR door does. It actually opens better. His cowl frame might even work also. The cowl frame is what the door hinge bolts to.
CR does not use original style latches. They use a bearclaw type latch. The bearclaw receptical bolts into the body and the pin bolts into the door.
Look at my photos (the camera icon under my user name). You will see the cowl bar in one or more of my photos. If you need any other pictures just let me know of what and I will post them with my other photos.
