4cyl radiator mounts
 

I was outside checking the coolant in my 4k and noticed my top radiator mount was broken off. This means the bottom is secured, but the top isnt, and it moves forward and back with vehicle movement. I have an aftermarket (Modine, all metal) radiator and was only able to secure one top mount, the one on the drivers side. It held fine, I think my one trip around the rally course forced it to snap off. How are the tiny mounts secured? Do I have to go behind the front top fender, or what else can I do to hold down the front of the radiator on top?
TIA
