Here we weld using our $300 MIG welder. Before commencing this operation, we were sure to fully assemble the loop and position it just right, and mark where the crosspiece should go. While BMR's alignment holes helped somewhat, we actually had to shift the crosspiece laterally just a touch from being centered on the factory floorpan holes, so that the upper part of the loop did not contact the side of the floorpan. Also note that the crosspiece is not symmetrical (due to different placement of the bolt holes on either side); care must be taken not to weld it in backwards!
