So my factory radiator finally **** the bed and sprung a leak from the passenger side tank.

Picked a new one op from O'Reillys since I was at work and couldn't wait for an aftermarket upgrade. Got it all square away but the new one has lots of play back and forth. I noticed the factory radiator had rubber pads and two additional studs that this one lacks.

What's the best way to secure the new rad and prevent it from wiggling around.

I'm not sure, but when I did mine I had to swap some stuff off the old one.

Without a pic it is hard to say, but if you had some scrap neoprene or EPDM laying around you could fab up some pads.

My replacement also has a little play. Didnt looked into that yet.
I think i glue some rubber padding on there and be done with it.

I didn't swap anything over as the stock rubber pads were glued or otherwise secured. I didn't even notice a spot for the condenser to bolt up to on top so I'm a little confused.

I've got some closed cell foam I might be able to scrounge up to act as a stand off.
