My understanding is that parts are mostly interchangeable in these cabs. What about the rotate mechanism? Looking at photos, it seems like this would be an interesting item to repro should the compatibility exist.
This should help:Any photos of the monitor mounting system and rotate mechanism would be helpful. Nothing looks difficult to manufacture from the pictures I've seen, and I read that the E3 "frame" is identical to E2. But if it were that simple I'd assume it would have been done.
That said, even if it doesn't drop in, I'm assuming a repro + mounting adapter could do the trick.
