2005 suburban
attempting to remove the GM receiver... cant get at the backside of the passenger side bolts on account the rear a/c unit is tight to open side of frame rail

theres a single visible bracket mounted to the a/c unit... i removed it, but theres something on the top of the big black plastic box thats still holding it... short of removing the entire bumper assemblyhttp://www.airforums.com/forums/images/smilies/angry.gif, i cant see any way to access the top of this unit...

does anyone have any experience with this?
is it connected with some type of 'snap' bracket? can i simply yank the thing off? it moves around quite a bit when the one bracket mount is removed...

TIA
