Passenger Door Handle

[Canton_Model_A's]

Morning crew:
Another question (Yes I have tons) I am working on replacing the passenger door handle this way I have a locking one in her. I take out the 2 screws, and pull the old one out, had to jiggle (nice technical term) and then it finally came out. I go to put the new one in (Purchased from Snyder's) and I get almost all the way seated but it seems it doesn't want to go the last 1/8-1/4" to seat down to screw it in.

Am I doing something wrong, is there something in the door I need to mess with and take the door card off?

Thanks!

Dave
