Edge comp and drag comp, repairs?

I've got an edge comp, and drag comp that need to be repaired. Called edge the other day and the tech said if they were built before 2006, then there nothing that can be done to fix them. The comp was built in 04, and the drag in 05...

Anyone have any insight as to where I can send these things to to have them repaired? One is for a gentleman I do a lot of repairs on his cattle pulling truck, and he says these boxes help out tremendously while pulling heavy.

Any help would be greatly appreciated!

You might see if you can get a different tech at edge, they repaired an old ez for me a few years back.

Ok I'll try them again and see if I get lucky
