Thanks to all for your suggestions.

I did try IPD, dealers, VCOA ads in the back of ROLLING, to try to track down the part etc. Noone has the part. It has been unavailable for a very long time.

So after much debate, my mechanic and I agreed to attempt a refurbishment. I bought all of the parts available for a redo - mostly o-rings and small rubber parts - also new manifold gasket. We soaked the breather box in cleaning fluid and after working at it, we were able to clean it up relatively well.

Car runs better than it has in a long time. Much less likely to stall out. But I still haven't completely figured out the stalling issue - cleaned the throttle body, but it still tends to stall out at stop lights, especially when its 85 degrees plus outside. But the breather box is fixed!
