Yeah, seems most stands are still designed to receive axle tubes, long after axle tubes have become the exception. Sometimes they do sit nicely under suspension components, but usually not frame fails or bodies.

I typically just place a flat block of sacrificial wood under the rubber pads on the MB, then let my stands crush right into the wood. Not optimal, but realistically they are not prone to slipping when dug in like that.

A nice flat-topped stand with a thick rubber pad would be ideal for most cars these days.
May weld up something someday. Maybe I could market them...
