Werner Jagusch Crossovers Damaged on Delivery - Can I Repair?

Hi All,

Long time first time. I just bought my dream speakers - Altec 846A w/ Werner Jagusch crossovers - but the Xovers took a spill in transit. Let's just say they were bounced around a good bit (through no fault of mine). A couple of terminal connectors broke off, pieces came unglued from the board... but nothing that seemed to say they were 100% destroyed.

I've negotiated with the seller on the issue, so at this point I'm mostly trying to determine if I can salvage these crossovers without ordering new ones, and if I risk damaging any of my equipment by hooking them up.

I've already got new connectors soldered on and everything glued back into place, but the one issue I'm concerned about are the "C-Cores" around the inductors. One of them came "unglued" and split apart, and the other has gaps in it where the epoxy can be seen.

Can I re-epoxy these back together? And if so, what's the appropriate product to use in this situation?
I've written to Werner but haven't heard back yet. Here are a couple of pictures of the units and the C-Cores, would appreciate any help if someone out there is knowledgable on this issue!
