*** UPDATE ****
I found that it came off in one piece. 19 years of decaying leaves were interfering with its removal.

Trying to do some maintenance on my AC unit. Can someone tell me if the shroud lifts off as one piece, two halves or other (after removing the 4 bolts)? It seems a little stuck, but I was cautious about forcing it until I'm sure of how it should come off. Thanks.
