Interesting update on "crappy" repro fan shrouds

Mine warped at the top. Kind of hard to tell in the picture but it sagged around 1/2":

340sFastback, curious to know how you have your shroud mounted to the rad. Are those bolts through u-nuts on the rad? Studs? Are there nuts between the shroud and rad that fit into those mount cavities on the backside of the shroud? Separate mounting brackets attached to the rad?
