So many different types of AC and stabilizers over the years. And-they might not be "original" equipment. Brand name of AC would be helpful. As for the stabilizers, I have a 2012 210UDS. The stabilizers come in all different sizes, mine were BAL 23025 17-inches. https://smile.amazon.com/BAL-23025-T..._t1_B002P2YTIA
Most stabilizers come without the foot pads.
This AC shroud is a common size for dometic, but to be sure, measure yours. https://smile.amazon.com/Dometic-331...motive&sr=1-17
