bad 454 engine mount?

[3x2GTO]

Backed my 1985 K30 up a hill today and heard the fan come in contact with the lower part of fan shroud, barely hitting and it stopped once I was on level ground or going forward. I looked underneath truck, the engine mount rubbers looked collapsed and the oil pan was almost resting on the crossmember, hopefully new mounts will fix. My truck was hit in the front at some time in the past, both frame horns have a couple of inches of damage on each. Do you think this is an engine/frame mount issue or maybe frame damage?
