Is this anything to worry about? They are completely missing on the other side....

 

Nothing to major, but it is best to replace. They are cheep and these ones are easy to install. http://www.summitracing.com/parts/SLF-00250/

 

I'm still searching for another pair of leafs with the same dimensions only with a taller height out of a different vehicle so I don't have to add in leafs to level the rear with the front when I do a lift.

Thanks for the recommendation!

 

This site has leaf spring dimensions. But I would suggest just to get keep your top leaf and replace the lowers with leafs with more arch when loaded. http://www.generalspringkc.com/index.php

 

Good idea! I never thought of keeping just the top leaf for mounting purposes.
