After removing the hoses, lossening the shroud, and popping the clips
on each of the radiator on my 380sl, I can't get it to budge, though I
thought that it would just slide up.

Is there some trick to getting it out? I notice that there are rubber
grommets just inside the clips on the top of each side. Do these have
to be removed first, or do they just slide up with the radiator?

Thanks for any help anyone can give me on this.
