Where to get a non flat coil spring isolator?

[Stomis]

Im running bronco coils on the trooper. My front lower buckets I made are flat. The end of the coil that lands on the bucket is just cut. Theres no flat last coil or anything like that.

I was looking for some isolators that have minimal lift are 4in ID and 5.5OD that have that height change built into them.

I know its not really necessary to do but does anyone happen to have an idea of where to get some generic things like this?

Energy suspension has plenty of flat generic isolators and has 3/4in lift isolators with that gradual twist for specific vehicle but its getting annoying trying to find an OEM fit.

Not isolators but some of the bronco places sell the coil cups separate.

I have looked for isolators too never found one

They used to sell a rubber "ring" to boost sagging coil springs on cars years ago,that you could wind around the coils,it was about 1-1/2" thick....perhaps you can still find some and use one of those as the base pad..I think "Superior" used to make them,they also sold the longer leaf spring shackle links,helper springs,etc...
