does anyone happen to know the size of the nut that holds the radiator to the ac condenser? the side on the condenser is a bolt, then the bracket goes over a stud on the top of the radiator. Upon removal, I snapped one of the studs and the nut is all but welded on to it.
I got one off fine and was going to go play match the nut at lowes, but that just doesnt sound like fun today......

 

hmm, not sure if my 1996 XJ is the same setup, but if I understand correctly it sounds like the same system. That nut that is stuck on the bolt is supposed to be that way as it sits in a rubber grommet on the a/c cooler unit.

on mine, the rubber grommets had just about disappeared when i changed the radiator last weekend.

i pieced it together by getting generic grommets at Autozone and then filling the space around with plenty of black RTV silicone. i think there is supposed to be some vibration dampening in between the a/c unit and the radiator.
