Question about rear springs.

When I bought my car it was on air bags. Since the engine, transmission and rear end swap I'm going back to springs. It appears there is a threaded hole in the pocket where the spring meets the chassis at the top. Is there supposed to be any type of clip or whatever to hold the spring up in the pocket ? The springs are 2" lowering springs and my concern is if the car was ever put on a 2 post lift the spring would fall out.

Thanks.

No clip I know about. I have 1” lower springs and mine are close.
Suggest some limitin straps.
