Front upright channel welded in, note the top is open to allow epoxy primer to be sprayed in. I put in a cross brace after refitting the front subframe to help it stay aligned. The mounting for the subframe has been fully seam welded at the sides , I will seam weld it underneath once I can rotate it on the jig for now it is stiched and spot welded. ditto the anti-roll bar mount.
