Pentium 4 Cpu Cooling

Have a machine in the shop Pentium 4 1.8 that was randomly locking up. Found that the heatsink cooling fan with the plastic clips was only connected on one side. Problem is the black plastic frame that is mounted to the MB is broken, so the clips will not lock when you push the levers. Any way to replace the the part on the MB, or any other methods that other shops use if they run across this? I could just put another MB in it, I suppose. Tks in advance.

Never seen one broken..............Good thing I have a box of spares.

Intel or the MB manufacturer may help.........

Tks for answering. First one I've seen also. MB is Biostar M7SXG, nothing on their website. Probably just put another MB in it, get it out of the shop.
