How To Replace Trunk Torsion Springs with Lift Struts

@retroron So you created mounting brackets that attach to the arm and the bracket? This requires no drilling on the arm? My concern has been that if I were to drill the arm, I might compromise it and have it bend or break.

And did you put sealed ball bearings at the ends of the arms? Very nice!
I welded bungs into the arm for bracket at the apex, you can see the brackets in the picture above they are triangular with a hole in the center. You can buy the stud attachment bracket from Guden. It will serve the same purpose as the bracket I made. If you weld the brackets to the arm it won't weaken it. Yes, I put sealed bearings at the end of the arm. I drilled and tapped the truck stud for a 10-32 screw to hold the bearing in place.
