Looking for a Goodmans Magnum K2 Midrange and Tweeter.

I recently purchased a set of Magnum K2's on eBay that were supposedly tested and working. After getting them collected and hooking them up I discovered the mid and tweeter in one of the units had gone!

I opted to get a partial refund and repair them as the condition of the cabinets is excellent and it's too much cost/effort to return them to the other end of the country. I'm on the lookout on eBay but thought I'd post here too.. cheers!
