It's been a while since I did my last radiator swap. Are the fan mounts welded to the radiator or what? I remember the fan drops into notches at the bottom of the radiator and bolts in at the top, but I'm having a hard time picturing it exactly. I'm looking to run lt1 fans on a non lt1 radiator and need to figure out the correct way to mount them.
If anyone has some pics or can just give a good description to get my memory going it'd be appreciated.
