When I was fitting up the USCT boxes in my 65, I checked the cut on the rail to verify it was square with the old mount area before welding. It was fine there but when I used my long level for a straight edge , clamped it to the inside of the spring box with the other end towards the where the new shackle would be going and found that straight edge of the level was in the old shackle area. Glad I caught that before I welded it in otherwise the springs would not have been inline with the rails. Good to go now plus I extended the SFC, past the old mount area, into the existing rail so that with the cuts and welding they all got tied together. One of the other members mentioned that to me before I got into that part of the car so it was an easy add on for the connector.

As I mentioned in the previous post, the USCT instructions for the spring boxes blow. They give you two choices, quick and dirty or spend some time squaring them up. On both you cut the rail so it's flush with the oe spring mount section which I did[ first picture]. However if you weld it in either way you end up, at least I did, with the spring heading off towards the old shackle hole[ second picture]. With the c-clamp on a diagonal, I was able to get the box pulled around so the spring would be in line with the rail like it's supposed to[ third picture]. I have a decent amount of it welded in now, will continue on it tomorrow or so. The unit not lining up in the new position could be an attachment error with the oe piece not being square to the rail. Who knows.
