Support bar is brazed and the rack is mounted from the rear. I didn't take any photos of brazing the front support bar. I brazed the front pillow blocks to the rack and brazed the support bar to the frame all at the same time. The rack was resting on the pillow blocks, the pillow blocks were bolted to the support bar, and the support bar was resting on the frame. This kept everything in alignment, no fixtures necessary.
