Engine Bay Insulation - where can I order a replacement?

My 08 451 had the recall done in 2018 but it is disintegrating again (maybe undiagnosed mice). Where can I buy replacement? My local mechanic can’t get parts from Mercedes dealer.
I checked Mercedes parts and the number I have doesn’t look like the insulation (451-682-00-61). This is the part number listed on my recall invoice as insulation.

I don't recall my 451 even having any insulation when I had it.

I always wondered if some heat resistant Dynamat would be better than stuff they include. Maybe even doubled-up?

On the 453 it seems really thin and loose, just a few plastic nuts holding some razor thin semi-rigid material in place.
