Vintage Air Top Mount Squeal

[cebra]

Anyone have a VA LS top mount and have squealing issues (or not)? I drove the vehicle for a long time before putting on the VA bracket/compressor and never heard any squeals/chirps. Now it does it a lot, I installed a shim they provide and it still does it every now and then. The compressor bracket is 1 groove wider than the accessories and it jumps grooves making the chirp. Guess I need to shim it more but I will have to call VA or make a new shim myself.
