74 doors open too far
 

Hi All-
I was wondering if anyone has any ideas on a fix for this issue. The doors on my 74 open too far and it ends up cracking the door where it is hitting the hinge I believe. I have read that this was an apparent issue for these cars and I've been told that there may have been a part on the hinge or something like a door check that would stop that from happening. Does anyone have any thoughts about this problem? I was wondering how to stop it from happening.
