They fit where I used them, I was hopeing they were a little stronger but will work anyway, I used them on an antique mower to cushion the pull for the horses

For my purposes, these were perfect. In fact, they were much stronger than I needed.

A JIS standard red medium duty 80x30mm die spring is spec'd to deflect at a rate of 7.03kgf/mm (see my answer to one of the user questions). Using a 64 kg weight and a cheap crane scale I measured 6.70kgf/mm on one that I received, and could well have had more than 0.33kgf/mm error in my measurement. Great price!
