Need replacement for black foam material inside Edge Tremolo front route
I have a 1989 540R in Jewel Blue. At some point the black padded material that's in the tremolo route cavity on the front of the body was removed. I'm guessing it probably started to disintegrate and was removed. I'd like to restore it to how it would have looked when new. Does anyone have suggestions on what I could stick in there or if there is an exact replacement available.
In case it's not clear what I'm talking about I've attached a picture.
