Hi Ka3muf,
We are not sure of the dimensions of the JR foam, but of course it simply needs to be the same as the original inserts for the 9Z case.
I hope you find this information helpful. You can also reach our Futaba support technical team at 217-398-8970, or via fax at 217-398-7721.
Sincerely,

I need to replace the foam in my 9Z case. I want to use a factory replacement, not the pull-apart stuff. If not available from Futaba, would the JR replacement fit adequately?
