Except it's not that way on GM factory mono's.
I had them on my Omega, but the weight exceeded their limit by about 600 lbs.
I took a set of carbon fiber springs from an Astro Van, and sawed both eyes off them and placed them under the mono's. You can drill that nub out with some good bits and a stout drill press and lots of oil. Then you can hold it all together with tradition round top spring bolts.
