[sdiy] Anvil Case Foam Rubber - Where to get it?

[Ken Elhardt]

I have a couple of big anvil cases for Jupiter-8 synths.  I was going
to sell one or both.  But when I opened them up for the first time in
11 years, the foam rubber is decomposing away and falling apart.  My
hand goes right through it.  Has anybody ever bought this stuff for
road cases and if so where?  It's a rather dense foam rubber that can
support heavy items without compressing too much.  I'd like to think I
could find a business within driving distance to purchase it as it
doesn't seem practical to mail order something of such a large size.

Thanks,
