ICE Tower CPU Cooling Fan for RPI A+ Model

Howdy Mates

Have a ICE tower, fits RPI B, obviously no issues. I want to over clock a A board, but the brackets line up with the board corner slots pins but does not sit flush due to the USB port placement (pics attached) and design of the A board

I don’t have access to a 3d printer or much knowledge on them, any one happen to know if you can order brackets for an A board?
I have looked with no luck.

I am think about grinding them, but I will have to take off a lot material on the one side

Open to suggestions.

Noob so I can only upload 1 photo
