Super Stock Springs and 60' foots

On my 002 / 003's it was as simple as a hunk of 1 1/2 " dia. aluminum.
Drilled a 3/4 " hole and a pressed a steel sleeve in it.....drilled that to 5/8ths , greased the bolt , done deal.
The 1 1/2" goes in with light pressure in a press. I wouldn't be surprised if you could pound them in with a dead blow hammer.
