Like a big refrigerator box? With two eyeholes and a muzzle slot?

I was thinking that since Ed's kit was mfg'd before high velocity/hyper velocity/sooper-dooper velocity .22 ammunition, it was the force of the breechblock/extractor slamming back that forced the extractor out. A stronger spring might help. Cleaning the crud out of the extractor cavity would help too.

Using only "target' .22LR ammunition would be a good idea as well. There's none available locally since the ban, which is why I tried whatever the LGS had left.

Maybe polishing the walls of the cavity would be beneficial too.

Dave, your attempt to remove the extractor sounds exactly like how I did it. IIRC, that plunger holds it down as well as in. No pin. The back has to kind of tilt up after the plunger is pushed back...
