PowerBook - Is it possible to replace a Danish Keyboard with an American Keyboard??

I purchased a used 15 inch Powerbook G4 1.67Ghz and it had a Danish keyboard installed in it. I am trying to replace it with an American keyboard. I did some research and ordered what I thought was the correct keyboard for the Powerbook. When I tried to install it, the female end of the "power-strip" (attached to the keyboard) that you insert into the male end (attached to the actual computer) does not fit -it is barely too wide.
I doublechecked the Keyboard model and I supposedly have the right one.
Has anyone ran into this issue before? Do I need to order a different keyboard model?
Help?!?
