Front Coil overs

[sub60]

Hi All, new to the site which I think is great. I am after some info as to how to run coil overs on a beetle torsion ball joint front end. I am presently building a track car but want to run coil overs and Iam unsure on the easiest way to remove or replace the torsion leaves to run the coil overs while still retaining the control arms. Has anybody here done it, any advice would be appreciated. Thanks Mike
